Opal and Japheth had the same amount of money at first. After Opal spent $133 on a wallet and Japheth received $39 from his father, Japheth had 3 times as much as money as Opal. How much money did Opal have at first?
| |
Opal |
Japheth |
| Before |
1 u + $133 |
3 u - $39 |
| Change |
- $133 |
+ $39 |
| After |
1 u |
3 u |
Opal and Japheth had the same amount of money at first.
3 u - 39 = 1 u + 133
3 u - 1 u = 133 + 39
2 u = 172
1 u = 172 ÷ 2 = 86
Amount that Opal had at first
= 1 u + 133
= 86 + 133
= $219
Answer(s): $219
