Sam had $55 more than Hazel. After Hazel spent
15 of her money, Sam had four times as much money as Hazel. How much money did Sam have at first?
| |
Sam |
Hazel |
| Before |
16 u |
5 u |
| Change |
|
- 1 u |
| After |
16 u |
4 u |
Amount that Sam had in the end
= 4 x 4 u
= 16 u
If Hazel had another $55 at first, the amounts that Sam and Hazel each had at first will be the same.
16 u = 5 u + 55
16 u - 5 u = 55
11 u = 55
1 u = 55 ÷ 11 = 5
Amount Sam had at first
= 16 u
= 16 x 5
= $80
Answer(s): $80
