Problema Solution

A baker can bake 40 cake per day at cost of x pesos each. He sells 5x + 5 each. Express profit p(x) of selling cakes per day as a function

Answer provided by our tutors

The profit per cake is 5x + 5 - x = 4x + 5. Since the total number of cakes sold is 40 the total profit is:

p(x) = 40*(5x + 5 - x)

p(x) = 40*(4x + 5)

p(x) = 160x + 200
