- Blueberry pie costs $9, lemon meringue cost $14
Step-by-step explanation:
<u>Set equations:</u>
- 13x + 12y = 285
- 3x + 12y = 195
<u>Solve by elimination. Subtract the second equation from the first:</u>
- 13x + 12y - 3x - 12y = 285 - 195
- 10x = 90
- x = 9
<u>Find the value of y:</u>
- 3*9 + 12y = 195
- 12y = 195 - 27
- 12y = 168
- y = 168/12
- y = 14
