37 as much money as Dana. Jane received another $46 from her father and Dana spent $10 on some markers. In the end, Jane and Dana had an equal amount of money. How much money did the girls have altogether in the end?

Before |
3 u |
7 u |
|
Change |
+ $46 |
- $10 |
|
After |
3 u + $46 |
7 u - $10 |
10 u + $36 |
Amount of money Jane and Dana has is the same in the end.
7 u - 10 = 3 u + 46
7 u - 3 u = 46 + 10
4 u = 56
1 u = 56 ÷ 4 = 14
Amount the girls have in the end
= 3 u + 46 + 7 u - 10
= 10 u + 36
= 10 x 14 + 36
= 140 + 36
= $176
Answer(s): $176
