Layla had
14 as much money as Luke at first. After Layla received $324 and Luke received $99, both of them had the same amount of money. How much did Luke have at first?
|
Layla |
Luke |
Before |
1 u |
4 u |
Change |
+ 324 |
+ 99 |
After |
1 u + 324 |
4 u + 99 |
The amount that Layla and Luke had in the end is the same.
1 u + 324 = 4 u + 99
4 u - 1 u = 324 - 99 = 225
3 u = 225
1 u = 225 ÷ 3 = 75
Amount that Luke had at first
= 4 u
= 4 x 75
= $300
Answer(s): $300
