Ava is starting a cake-baking business, and she has just spent $150 for equipment. She
figures that each cake will cost $4.50 to make, and she plans to sell her cakes for $12 each.
Ava wants to find the number of cakes, c, she must sell to break even. In other words, she
wants to know how many cakes she must sell before she has made as much money as she
has spent. Which equation can she use?
150+ 4.5c= 12c
150 4.5c= 12c
-
c(150+ 4.5) = 12c
Submit
4.5c+ 12c 150
4.5c + 150 = 12
150c + 4.5 = 12
