Solve the problem.A vendor has learned that, by pricing carmel apples at $1.00, sales will reach 128 carmel apples per day. Raising the price to $2.00 will cause the sales to fall to 76 carmel apples per day. Let f(x) be the number of carmel apples the vendor sells at x dollars each. Write a linear function that models the number of carmel apples sold per day when the price is x dollars each.
