Maya had
13 as much money as David at first. After Maya received $330 and David received $86, both of them had the same amount of money. How much did David have at first?
|
Maya |
David |
Before |
1 u |
3 u |
Change |
+ 330 |
+ 86 |
After |
1 u + 330 |
3 u + 86 |
The amount that Maya and David had in the end is the same.
1 u + 330 = 3 u + 86
3 u - 1 u = 330 - 86 = 244
2 u = 244
1 u = 244 ÷ 2 = 122
Amount that David had at first
= 3 u
= 3 x 122
= $366
Answer(s): $366
