3 people rent 18 movies altogether. I person would rent 6 movies
Answer:
Step-by-step explanation:
Let football cost be f and basketball cost be b
<u>We have two equations as per given:</u>
- 5f + 14b = 110
- 10f + 6b = 82.50
We need to find b, therefore we'll eliminate f
<u>To do so we'll double the first equation and subtract the second one:</u>
- 2(5f + 14b) - (10f + 6b) = 2(110) - 82.50
- 28b - 6b = 220 - 82.50
- 22b = 137.5
- b = 137.5/22
- b = 6.25
Each basketball costs $6.25
