Tom had $35 more than Yen. After Yen spent
17 of her money, Tom had twice as much money as Yen. How much money did Tom have at first?
| |
Tom |
Yen |
| Before |
12 u |
7 u |
| Change |
|
- 1 u |
| After |
12 u |
6 u |
Amount that Tom had in the end
= 2 x 6 u
= 12 u
If Yen had another $35 at first, the amounts that Tom and Yen each had at first will be the same.
12 u = 7 u + 35
12 u - 7 u = 35
5 u = 35
1 u = 35 ÷ 5 = 7
Amount Tom had at first
= 12 u
= 12 x 7
= $84
Answer(s): $84
