John had $58 more than Irene. After Irene spent
23 of her money, John had five times as much money as Irene. How much money did John have at first?
| |
John |
Irene |
| Before |
5 u |
3 u |
| Change |
|
- 2 u |
| After |
5 u |
1 u |
Amount that John had in the end
= 5 x 1 u
= 5 u
If Irene had another $58 at first, the amounts that John and Irene each had at first will be the same.
5 u = 3 u + 58
5 u - 3 u = 58
2 u = 58
1 u = 58 ÷ 2 = 29
Amount John had at first
= 5 u
= 5 x 29
= $145
Answer(s): $145
