Question

Erin spent $15.30 on ingredients for cookies she’s making for the school bake sale. How many cookies must she sell at $0.35 a piece to make a profit

Answer 1

Answer: 44

Explanation:

first set up an equation.

0.35c = 15.30

next you want to get c by itself so you divide both sides by 0.35.

0.35c/0.35 = 15.30/0.35

c = 43.7142857 then you round that to 44

Answer 2

she needs to sell at least 44 cookies to make a $0.10 profit

Explanation:

to find the answer all you have to do is divide 15.30 by 0.35
