Zane had $55 more than Victoria. After Victoria spent
17 of her money, Zane had thrice as much money as Victoria. How much money did Zane have at first?
| |
Zane |
Victoria |
| Before |
18 u |
7 u |
| Change |
|
- 1 u |
| After |
18 u |
6 u |
Amount that Zane had in the end
= 3 x 6 u
= 18 u
If Victoria had another $55 at first, the amounts that Zane and Victoria each had at first will be the same.
18 u = 7 u + 55
18 u - 7 u = 55
11 u = 55
1 u = 55 ÷ 11 = 5
Amount Zane had at first
= 18 u
= 18 x 5
= $90
Answer(s): $90
