Question

a. Suppose that a market research company finds that at a price of p = $31, they would sell x = 74 boxes of product each month. If they lower the price to p = $25, then more people would purchase the product, and they can expect to sell x = 80 boxes in a month’s time. Find the equation of the line for the demand equation. Write your answer in the form p = mx + b. (Hint: Write an equation using two points in the form (x,p)).
