Question

Ginger & Mary-Anne's Bakeshop makes triple chocolate brownies that cost $1.50 each. Past experience shows that 20% of the brownies will spoil. Assuming May wants a 40% markup based on cost and produces 200 brownies, what should each brownie sell for?

Answer 1

cost 200*1.50 = 300
brownies sold: .80 * 200 = 160
So you need to charge x per brownie so that
160x = 300 * 1.40
now finish it off
