Carli and Angela share a cell phone plan and split the bill each month. Last month, their total bill was $109. Carli went over her data limit on her phone, so her share of the bill was $15 more than Angela's to account for the overage charge. Which system of equations represents this situation?
Accepted Solution
A:
For this case, the first thing we must do is define variables. We have then: x = Carli's bill y = Angela's bill We have then: "their total bill was $ 109" x + y = 109 "Carli went over her data limit on her phone, so her share of the bill was $ 15 more than Angela's" x = y + 15 Answer: A system of equations that represents this situation is: x + y = 109 x = y + 15
