Abi had
15 as much money as Emily. Abi received another $39 from her father and Emily spent $9 on some markers. In the end, Abi and Emily had an equal amount of money. How much money did the girls have altogether in the end?

5 u |
|
Change |
+ $39 |
- $9 |
|
After |
1 u + $39 |
5 u - $9 |
6 u + $30 |
Amount of money Abi and Emily has is the same in the end.
5 u - 9 = 1 u + 39
5 u - 1 u = 39 + 9
4 u = 48
1 u = 48 ÷ 4 = 12
Amount the girls have in the end
= 1 u + 39 + 5 u - 9
= 6 u + 30
= 6 x 12 + 30
= 72 + 30
= $102
Answer(s): $102
