Tim had $56 more than Zoe. After Zoe spent
25 of her money, Tim had four times as much money as Zoe. How much money did Tim have at first?
| |
Tim |
Zoe |
| Before |
12 u |
5 u |
| Change |
|
- 2 u |
| After |
12 u |
3 u |
Amount that Tim had in the end
= 4 x 3 u
= 12 u
If Zoe had another $56 at first, the amounts that Tim and Zoe each had at first will be the same.
12 u = 5 u + 56
12 u - 5 u = 56
7 u = 56
1 u = 56 ÷ 7 = 8
Amount Tim had at first
= 12 u
= 12 x 8
= $96
Answer(s): $96
