1. Consider your decision about whether to go skiing for the weekend. Suppose that​transportation, lift​tickets, and accommodation for the weekend costs $350. Suppose also that restaurant food for the weekend will cost $90​, which is twice the amount normally spent on weekend meals. ​ Finally, suppose that you have a weekend job that you will have to miss if you go​skiing, which pays you $150 (after tax) per weekend.

What is the opportunity cost of going​skiing? Do you need any other information before computing the opportunity ​cost?

2. Suppose that the market for frozen orange juice is in equilibrium at a price of $2.00 per can and a quantity of 4,200 cans per month. Now suppose that at a price of $3.00 per can, the quantity demanded falls to 3,000 cans per month and the quantity supplied increases to 4,500 cans per month.

a. Calculate the price elasticity of demand for frozen orange juice between the price of $2.00 and $3.00. Is the demand elastic or inelastic?

b. Calculate the price elasticity of supply for frozen orange juice between the price of $2.00 and $3.00. Is the supply elastic or inelastic?

3. From the following quotations, what if, anything, can you conclude about elasticity of demand.

a. ‘’Good weather resulted in records wheat harvest and sent wheat prices tumbling. The result has been disastrous for many wheat farmers.’’

b. ‘’Ridership always went up when bus fares came down, but the increased patronage never was enough to prevent a decrease in overall revenue.’’

F ​$60 260,000
G $65 230,000
H ​$70 190,000

b. Compute the price elasticities of demand between points A and​ B, B and​ C, C and​ D, and so on.

d. Over what range of prices is the demand for video games elastic? Explain.

e. Over what range of prices is the demand for the video games inelastic? Explain.

7. Visit the website of a newspaper or a news agency such as cbc.ca, and look for the news items concerning government policy or business decisions that involve the basic economic concept of opportunity cost. Write a brief explanation of the opportunity cost of the decision that you selected.
