II. Assume the inverse demand for gas in the north of a country is Dn(qn) = 700 qn while in the south the inverse demand function is Ds (qs ) = 710 3qS . There is only one brand of gas stations that has a constant marginal cost c = 100 and operates in both parts of the country (q is measured in gallons and p in cents).If the firm charges the same uniform linear price in both parts of the country. Write the problem of the firm. What would be the equilibrium quantities qN and qS.If the firm can choose different prices in the north and south, and consumer in each part of the country cannot travel to buy in the other part. Write the problem of the firm.

S Question 2: (2.0pts) There are ten mistakes in the passage. Underline the mistakes and correct them. People usually complaint that they never have enough time to accomplish tasks. The hours and minutes seems to slip away before many planning chores get done. According to time management experts, the mainly reason for this is that most people fail to set priorities about what to do first. They get tiring down by trivial, time-consuming matters and never complete the important ones. One simple solution often used by those at the top is kept lists of tasks to be accomplished daily. These lists order jobs from most essential to less essential and are checked regular through the day to access progress.

People who do not keep lists often face the end of the work with uncertain over the significance of their accomplishments, which over time can contribute to serious problems in mental and physics health.
