Carl had $54 more than Zoe. After Zoe spent
23 of her money, Carl had five times as much money as Zoe. How much money did Carl have at first?
| |
Carl |
Zoe |
| Before |
5 u |
3 u |
| Change |
|
- 2 u |
| After |
5 u |
1 u |
Amount that Carl had in the end
= 5 x 1 u
= 5 u
If Zoe had another $54 at first, the amounts that Carl and Zoe each had at first will be the same.
5 u = 3 u + 54
5 u - 3 u = 54
2 u = 54
1 u = 54 ÷ 2 = 27
Amount Carl had at first
= 5 u
= 5 x 27
= $135
Answer(s): $135
