Aaron had
13 as much money as Grace at first. After Aaron received $316 and Grace received $62, both of them had the same amount of money. How much did Grace have at first?
|
Aaron |
Grace |
Before |
1 u |
3 u |
Change |
+ 316 |
+ 62 |
After |
1 u + 316 |
3 u + 62 |
The amount that Aaron and Grace had in the end is the same.
1 u + 316 = 3 u + 62
3 u - 1 u = 316 - 62 = 254
2 u = 254
1 u = 254 ÷ 2 = 127
Amount that Grace had at first
= 3 u
= 3 x 127
= $381
Answer(s): $381
