Riordan |
Charlotte |
Before |
1 u |
3 u |
Change |
+ 283 |
+ 87 |
After |
1 u + 283 |
3 u + 87 |
The amount that Riordan and Charlotte had in the end is the same.
1 u + 283 = 3 u + 87
3 u - 1 u = 283 - 87 = 196
2 u = 196
1 u = 196 ÷ 2 = 98
Amount that Charlotte had at first
= 3 u
= 3 x 98
= $294
Answer(s): $294
