Fabian was out at a restaurant for dinner when the bill came. His dinner came to $35. He wanted to leave a 15% tip. How much was his meal plus the tip, before tax, in dollars and cents?
Using the multiplication and addition operations, if Fabian leaves a 15% tip, his meal plus the tip, before tax, is $40.25.
What are multiplication and addition operations?Multiplication and addition operations are two of the four basic mathematical operations.
Multiplication involves the use of multiplicand, multiplier, multiplication operand, equal symbol, and product.
The addition operation involves using the two addends, the equal sign, and the sum.
Dinner cost before tip and tax = $35
Tip = 15%
Total cost before tax = 115% (100 + 15)
Dinner cost after tip = $40.25 ($35 x 1.15)
Thus, mathematically, Fabian will spend $40.25 for the dinner before tax.

Eli and Claire work at a dry cleaners ironing shirts. Eli can iron 15 shirts per hour,
and Claire can iron 20 shirts per hour. Eli and Claire worked a combined 17 hours
and ironed 300 shirts. Graphically solve a system of equations in order to determine
the number of hours Eli worked, x, and the number hours Claire worked, y.
Answer:
∴ Eli worked for 8 hours and Claire worked for 9 hours
Step-by-step explanation:
Let us form the two equations then graph them
∵ Eli worked for x hours
∵ Claire worked for y hours
∵ Eli and Claire worked a combined 17 hours
∴ x + y = 17 ⇒ (1)
∵ Eli can iron 15 shirts per hour
∵ Claire can iron 20 shirts per hour
∵ They ironed 300 shirts together in 17 hours
→ Multiply x by 15 and y by 20, then add the products and equate their
sum by 300
∴ 15x + 20 y = 300 ⇒ (2)
Now let us find 2 points in each equation and draw the two lines which represent the two equations
→ In equation 1, put x = 0
∵ x = 0
∵ 0 + y = 17
∴ y = 17
∴ The first point is (0, 17)
→ Put y = 0 and find x
∵ y = 0
∴ x + 0 = 17
∴ x = 17
∴ The second point is (17, 0)
→ In equation 2, put x = 0
∵ x = 0
∵ 0 + 20y = 300
∴ 20y = 300
→ Divide both sides by 20
∴ y = 15
∴ The first point is (0, 15)
→ Put y = 0 and find x
∵ y = 0
∴ 15x + 0 = 300
→ Divide both sides by 15
∴ x = 20
∴ The second point is (20, 0)
Draw the first line using points (0, 17) and (17, 0)
Draw the second line using points (0, 15) and (20, 0)
The graph is attached down
From the graph
The red line represents equation (1)
The blue line represents equation (2)
The two lines intersected at point (8, 9) which is the solution of the system of equations
∴ The solution of the two equations is (8, 9)
∴ Eli worked for 8 hours and Claire worked for 9 hours
You have 2500 ft.² of selling space you want to reserve at least 125 ft.² for each product category will carry 30% of the space will be used for isles how many categories can you carry
The most appropriate choice for percentage will be given by-
14 categories can be carried
What is Percentage?
Percentage is a ratio expressed as a percentage of 100.
Total area of selling space = \(2500 ft^2\)
Percentage of space used for isles = \(30\) %
Area of space used for isles = \(\frac{30}{100} \times 2500\)
= \(750 ft^2\)
Area of space left = \(2500 - 750\)
= \(1750 ft^2\)
Area of space reserved for each category = \(125 ft^2\)
No of categories = \(\frac{1750}{125}\)
= \(14\)
14 categories can be carried

In a long run, if a company becomes absolete what does it do to the LRATC?
In the long run, if a company becomes obsolete and cannot compete effectively in the market, it will eventually exit the market.
This will lead to a reduction in the overall level of industry output and a shift in the market supply curve. As a result, the long-run average total cost (LRATC) of the remaining firms in the market may increase or decrease depending on the specifics of the situation.
If the exiting company had high production costs, its exit may lead to a decrease in the industry's LRATC as the remaining firms may experience a reduction in input prices or an increase in market share. However, if the exiting firm was a low-cost producer, its exit may lead to an increase in the industry's LRATC due to the loss of economies of scale or increased competition.

Solve the following initial value problem. y′′−2y′+y=1+4e^t,y(0)=3,y′(0)=1
Given the initial value problem:y″ - 2y′ + y = 1 + 4e^t , y(0) = 3 , y′(0) = 1
To solve the above initial value problem, we follow the steps mentioned below:
Step 1: Find the roots of the characteristic equation obtained by setting the left-hand side of the differential equation to zero. The characteristic equation is given by:\(r^2 - 2r + 1 = 0\)
The above quadratic equation can be factorized as:\((r - 1)^2 = 0\)
The roots of the characteristic equation are:r1 = r2 = 1. Since we have two equal real roots, the general solution of the differential equation can be written as:\(y = (c1 + c2 t) e^t\) where c1 and c2 are arbitrary constants.
Step 2: We have to find the particular solution of the non-homogeneous part of the differential equation. The non-homogeneous part of the differential equation is given by:\(1 + 4e^t\)
Let the particular solution be of the form:\(y_p = a + bt + ce^t + de^t]\)
Substituting y_p in the differential equation, we get:\(2d = 1 + 4e^t\)
On integrating, we get:\(d = 0.5t + 0.5 e^t\)
Substituting the value of d, we get:\(y_p = 0.5t + 0.5 e^t\)
The general solution of the given differential equation is:\(y = (c1 + c2 t) e^t + 0.5t + 0.5 e^t\)
To find the values of c1 and c2, we use the initial conditions given as follows:y(0) = 3y′(0) = 1
On substituting the values of y and y′ in the above equations, we get:c1 + 0.5 = 3c1 + c2 + 0.5 = 1
Solving the above two equations, we get:c1 = 1.5 , c2 = -0.5
The solution of the given initial value problem is:\(y = (1.5 - 0.5t) e^t + 0.5t + 0.5 e^t.\)

Find the derivative of the function by using the definition of derivative: f(x) = (x+1)²
The derivative of the function f(x) = (x+1)² is f'(x) = 2x + 2. To find the derivative of the function f(x) = (x+1)² using the definition of the derivative:
We will apply the limit definition of the derivative. The derivative of a function represents the rate of change of the function at any given point.
Step 1: Write the definition of the derivative.
The derivative of a function f(x) at a point x is defined as the limit of the difference quotient as h approaches zero:
f'(x) = lim(h→0) [f(x+h) - f(x)] / h
Step 2: Apply the definition to the given function.
Substitute the function f(x) = (x+1)² into the difference quotient:
f'(x) = lim(h→0) [(x+h+1)² - (x+1)²] / h
Step 3: Expand and simplify the numerator.
Expanding the square terms in the numerator, we have:
f'(x) = lim(h→0) [(x² + 2xh + h² + 2x + 2h + 1) - (x² + 2x + 1)] / h
Simplifying, we get:
f'(x) = lim(h→0) [2xh + h² + 2h] / h
Step 4: Cancel out the common factor of h in the numerator.
We can cancel out the factor of h in the numerator:
f'(x) = lim(h→0) [2x + h + 2]
Step 5: Evaluate the limit.
As h approaches zero, the term 2x + h + 2 does not depend on h anymore. Therefore, the limit of the expression is simply the expression itself:
f'(x) = 2x + 2
