Mia had
13 as much money as Salik at first. After Mia received $303 and Salik received $87, both of them had the same amount of money. How much did Salik have at first?
|
Mia |
Salik |
Before |
1 u |
3 u |
Change |
+ 303 |
+ 87 |
After |
1 u + 303 |
3 u + 87 |
The amount that Mia and Salik had in the end is the same.
1 u + 303 = 3 u + 87
3 u - 1 u = 303 - 87 = 216
2 u = 216
1 u = 216 ÷ 2 = 108
Amount that Salik had at first
= 3 u
= 3 x 108
= $324
Answer(s): $324
