Betty and Reggie had the same amount of money at first. After Betty spent $83 on a wallet and Reggie received $73 from his uncle, Reggie had 3 times as much as money as Betty. How much money did Betty have at first?
| |
Betty |
Reggie |
| Before |
1 u + $83 |
3 u - $73 |
| Change |
- $83 |
+ $73 |
| After |
1 u |
3 u |
Betty and Reggie had the same amount of money at first.
3 u - 73 = 1 u + 83
3 u - 1 u = 83 + 73
2 u = 156
1 u = 156 ÷ 2 = 78
Amount that Betty had at first
= 1 u + 83
= 78 + 83
= $161
Answer(s): $161
