Jenson had $30 more than Gwen. After Gwen spent
25 of her money, Jenson had five times as much money as Gwen. How much money did Jenson have at first?
| |
Jenson |
Gwen |
| Before |
15 u |
5 u |
| Change |
|
- 2 u |
| After |
15 u |
3 u |
Amount that Jenson had in the end
= 5 x 3 u
= 15 u
If Gwen had another $30 at first, the amounts that Jenson and Gwen each had at first will be the same.
15 u = 5 u + 30
15 u - 5 u = 30
10 u = 30
1 u = 30 ÷ 10 = 3
Amount Jenson had at first
= 15 u
= 15 x 3
= $45
Answer(s): $45
