Isaiah had
13 as much money as Amelia at first. After Isaiah received $235 and Amelia received $87, both of them had the same amount of money. How much did Amelia have at first?
|
Isaiah |
Amelia |
Before |
1 u |
3 u |
Change |
+ 235 |
+ 87 |
After |
1 u + 235 |
3 u + 87 |
The amount that Isaiah and Amelia had in the end is the same.
1 u + 235 = 3 u + 87
3 u - 1 u = 235 - 87 = 148
2 u = 148
1 u = 148 ÷ 2 = 74
Amount that Amelia had at first
= 3 u
= 3 x 74
= $222
Answer(s): $222
