Problema Solution

The cost C of producing x number of scientific calculators is given by C = 4.50x + 3000 and the revenue R from selling them is given by R = 16.50x

Find how many calculators must be sold to break even?

Answer provided by our tutors

profit = revenue - cost


we want to calculate 'x' when profit = 0

revenue = cost


16.50x = 4.50x + 3000

solving for 'x' we have x=250


250 calculators must be sold to break even
