Levi had
15 as much money as Robert at first. After Levi received $170 and Robert received $66, both of them had the same amount of money. How much did Robert have at first?
|
Levi |
Robert |
Before |
1 u |
5 u |
Change |
+ 170 |
+ 66 |
After |
1 u + 170 |
5 u + 66 |
The amount that Levi and Robert had in the end is the same.
1 u + 170 = 5 u + 66
5 u - 1 u = 170 - 66 = 104
4 u = 104
1 u = 104 ÷ 4 = 26
Amount that Robert had at first
= 5 u
= 5 x 26
= $130
Answer(s): $130
