Tom had $56 more than Abi. After Abi spent
25 of her money, Tom had thrice as much money as Abi. How much money did Tom have at first?
| |
Tom |
Abi |
| Before |
9 u |
5 u |
| Change |
|
- 2 u |
| After |
9 u |
3 u |
Amount that Tom had in the end
= 3 x 3 u
= 9 u
If Abi had another $56 at first, the amounts that Tom and Abi each had at first will be the same.
9 u = 5 u + 56
9 u - 5 u = 56
4 u = 56
1 u = 56 ÷ 4 = 14
Amount Tom had at first
= 9 u
= 9 x 14
= $126
Answer(s): $126
