Explanation:
<u>a.what happens to the price of coffee beans?</u>
In this case, when there is a phenomenon like a hurricane that destroys half the harvest, the supply of coffee beans consequently decreases, the quantity decreases and the price increases.
<u>b. What happens to the price of a cup of coffee? What happens to the total expenditure on cups of coffee?</u>
When the price of the main input for the production of coffee cups increases and the supply decreases, it appears as an increase in the price of a cup of coffee and a decrease in the amount of coffee cups available on the market.
As they have an inelastic demand, coffee cups with a higher price correspond to an increase in total coffee expenses.
<u>c.What happens to the price of a cup of donuts? What happens to the total expendiure on donuts?</u>
In this case, donuts and coffee are complementary, so when there is an increase in the price of coffee and a decrease in the quantity demanded, there is also a decrease in the demand for donuts. So if the demand for donuts decreases, their price also decreases and the total expenditure on donuts decreases.
