Isaiah had
14 as much money as Grace at first. After Isaiah received $174 and Grace received $75, both of them had the same amount of money. How much did Grace have at first?

Isaiah |
Grace |
| Before |
1 u |
4 u |
| Change |
+ 174 |
+ 75 |
| After |
1 u + 174 |
4 u + 75 |
The amount that Isaiah and Grace had in the end is the same.
1 u + 174 = 4 u + 75
4 u - 1 u = 174 - 75 = 99
3 u = 99
1 u = 99 ÷ 3 = 33
Amount that Grace had at first
= 4 u
= 4 x 33
= $132
Answer(s): $132
