Problem 1

In a sales market, the supply and demand equations of a product have been identified.

Qd = 550 - 100 P

Qo = 250+ 150P

According to the most recent data from the economy, the cost of workers (salary) rose by $ 150. How do you think the breakeven point of that market will be affected?

Problem 2

Determine the equilibrium price in the following market that reflects the sale of motor gasoline last month.

Qd = 500 - 75 P

Qo = 250 + 25 P

Two events have affected the gasoline market this week:

People who buy gasoline reflect a decrease in their income of $ 50 a month. On the vendor side, 75 new gasoline stations have been opened.

What consequences will these events have on the market equilibrium point?
