When they charged $4 for a cup of coffee, they sold 185,000 Ibs of coffee in one month. Find a linear function C(x) that models how many pounds of coffee sold, C(x), based on the price per cup of coffee, x.
Expert Solution
Step 1

Given

                 C(x) = Coffee (in pounds ) sold.

                      x = price per cup

And

When x = $2.50 , C(x) = 230,000 lbs

When x = $4 , C(x) = 185,000 lbs

C(x) is linear function of x.
