Harper |
Olivia |
| Before |
1 u |
3 u |
| Change |
+ 247 |
+ 81 |
| After |
1 u + 247 |
3 u + 81 |
The amount that Harper and Olivia had in the end is the same.
1 u + 247 = 3 u + 81
3 u - 1 u = 247 - 81 = 166
2 u = 166
1 u = 166 ÷ 2 = 83
Amount that Olivia had at first
= 3 u
= 3 x 83
= $249
Answer(s): $249
