Brett wants to paint his master bedroom. the paint costs $21 per gallon and the primer costs $15 per gallon. he does not want to exceed $185 for the paint and primer. he has determined that he needs at least 5 gallons of paint and primer in total. if p represents the number of gallons of paint and r represents the number of gallons of primer, which system of inequalities represents brett’s situation?

Explanation:

Two inequalities can be derived from the question.

1. Total Cost Inequality

If paint (p) costs $21 per gallon, primer (r) costs $15 per gallon, and Brett does not want to exceed $185, we can represent this by the inequality below.

.

This means total cost of paint and primer will be less than or equal to $185.

2. Total Quantity Inequality

Brett determined that he needs at least 5 gallons in total, and we represent this by the inequality below.

This means total quantity of paint and primer must be greater than 5.

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.
