Isabella had
16 as much money as Joseph at first. After Isabella received $229 and Joseph received $79, both of them had the same amount of money. How much did Joseph have at first?
|
Isabella |
Joseph |
Before |
1 u |
6 u |
Change |
+ 229 |
+ 79 |
After |
1 u + 229 |
6 u + 79 |
The amount that Isabella and Joseph had in the end is the same.
1 u + 229 = 6 u + 79
6 u - 1 u = 229 - 79 = 150
5 u = 150
1 u = 150 ÷ 5 = 30
Amount that Joseph had at first
= 6 u
= 6 x 30
= $180
Answer(s): $180
