You are in a line at the bank drive-through and 3 cars are in front of you. You estimate that the clerk is taking about six minutes per car to serve. How long do you expect to wait in line?

I will wait in line for about 18 minutes

Explanation:

If I am in a line at a bank drive through and 3 cars are in front of me  and the clerk is taking about 6 minutes per car to serve , the number of minutes I should expect to wait in line can be computed as follows:

Since the clerk uses 6 minutes to serve a single car, their are 3 cars before me. This means the clerk will serve those 3 cars before me.  Mathematically,

if 1 car uses 6 minutes

 3 car will use ? minutes

cross multiply

3 × 6

3 × 6 = 18 minutes

I will wait in line for about 18 minutes

answer: in the short-run firms will respond by raising the price of turkey.

explanation: initially the long-run equilibrium is at a price of $5 per pound of turkey and a quantity of 50 million pounds per year. now, when webmd claims that a protein found in turkey will increase your expected lifespan by 4 years. the consumers demand for turkey will increase at every price shifting the demand curve to the right from d1 to d2. while, there will be no change in the supply curve in the short-run as it is not possible for producers to adjust supply so quickly. as a result the new equilibrium will occur at a higher price and a higher quantity of turkey.

thus, in the short run firms will respond by increasing the price of turkey, selling more quantity at a higher price and earning economic profits.
