Charlie had $40 more than Kylie. After Kylie spent
17 of her money, Charlie had twice as much money as Kylie. How much money did Charlie have at first?
| |
Charlie |
Kylie |
| Before |
12 u |
7 u |
| Change |
|
- 1 u |
| After |
12 u |
6 u |
Amount that Charlie had in the end
= 2 x 6 u
= 12 u
If Kylie had another $40 at first, the amounts that Charlie and Kylie each had at first will be the same.
12 u = 7 u + 40
12 u - 7 u = 40
5 u = 40
1 u = 40 ÷ 5 = 8
Amount Charlie had at first
= 12 u
= 12 x 8
= $96
Answer(s): $96
