Carl had $44 more than Shannon. After Shannon spent
17 of her money, Carl had thrice as much money as Shannon. How much money did Carl have at first?
| |
Carl |
Shannon |
| Before |
18 u |
7 u |
| Change |
|
- 1 u |
| After |
18 u |
6 u |
Amount that Carl had in the end
= 3 x 6 u
= 18 u
If Shannon had another $44 at first, the amounts that Carl and Shannon each had at first will be the same.
18 u = 7 u + 44
18 u - 7 u = 44
11 u = 44
1 u = 44 ÷ 11 = 4
Amount Carl had at first
= 18 u
= 18 x 4
= $72
Answer(s): $72
