Carl had $33 more than Gabby. After Gabby spent
15 of her money, Carl had four times as much money as Gabby. How much money did Carl have at first?
| |
Carl |
Gabby |
| Before |
16 u |
5 u |
| Change |
|
- 1 u |
| After |
16 u |
4 u |
Amount that Carl had in the end
= 4 x 4 u
= 16 u
If Gabby had another $33 at first, the amounts that Carl and Gabby each had at first will be the same.
16 u = 5 u + 33
16 u - 5 u = 33
11 u = 33
1 u = 33 ÷ 11 = 3
Amount Carl had at first
= 16 u
= 16 x 3
= $48
Answer(s): $48
