Jean and Tommy had the same amount of money at first. After Jean spent $7 on a wallet and Tommy received $77 from his aunt, Tommy had 4 times as much as money as Jean. How much money did Jean have at first?
| |
Jean |
Tommy |
| Before |
1 u + $7 |
4 u - $77 |
| Change |
- $7 |
+ $77 |
| After |
1 u |
4 u |
Jean and Tommy had the same amount of money at first.
4 u - 77 = 1 u + 7
4 u - 1 u = 7 + 77
3 u = 84
1 u = 84 ÷ 3 = 28
Amount that Jean had at first
= 1 u + 7
= 28 + 7
= $35
Answer(s): $35
