14 as much money as Christopher at first. After Rael received $331 and Christopher received $70, both of them had the same amount of money. How much did Christopher have at first?

Rael |
Christopher |
Before |
1 u |
4 u |
Change |
+ 331 |
+ 70 |
After |
1 u + 331 |
4 u + 70 |
The amount that Rael and Christopher had in the end is the same.
1 u + 331 = 4 u + 70
4 u - 1 u = 331 - 70 = 261
3 u = 261
1 u = 261 ÷ 3 = 87
Amount that Christopher had at first
= 4 u
= 4 x 87
= $348
Answer(s): $348
