Jake bakes and sell apple pies. he sells each pie for $5.75. the materials to make the pies cost 40$. the boxes jake pits the pies in cost $12.50 total. how many pies would jake need to sell to earn a profit of $50?

First, he would have to make his money back so he spend $52.50.
So if you add $50 to that you would get $102.50. Next you would divide that by $5.75. That gives you 17.82. So he would have to sell 18 pies to make a 50 dollar profit.
