Andy bakes and sells birthday cakes. To make two cakes he spends $12 on ingredients, and $1 on packaging for each cake. Andy sells each cake for $15. How much money does Andy make for each cake? Think carefully first, then make a decision:
Spending $12 on ingredients for 2 cakes, he spends 12 / 2 = $6 on ingredients per cake. Adding the cost of packaging, he spends 6 + 1 = $7 per cake. Selling each cake for $15, Andy's profit is 15 - 7 = $8 per cake. So, the answer is 8.
