Michael had
14 as much money as Joseph at first. After Michael received $171 and Joseph received $72, both of them had the same amount of money. How much did Joseph have at first?

Michael |
Joseph |
| Before |
1 u |
4 u |
| Change |
+ 171 |
+ 72 |
| After |
1 u + 171 |
4 u + 72 |
The amount that Michael and Joseph had in the end is the same.
1 u + 171 = 4 u + 72
4 u - 1 u = 171 - 72 = 99
3 u = 99
1 u = 99 ÷ 3 = 33
Amount that Joseph had at first
= 4 u
= 4 x 33
= $132
Answer(s): $132
