Abi and Cole had the same amount of savings at first. Then Abi spent
15 of her savings and Cole spent
23 of his savings. If Abi spent $1890 less than Cole, how much did each of them have at first?
|
Abi |
Cole |
Before |
5x3 = 15 u |
3x5 = 15 u |
Change |
1x3 = - 3 u |
2x5 = - 10 u |
After |
12 u |
5 u |
The amount that Abi and Cole had at first is the same. Make the amount that Abi and Cole each had the same. LCM of 5 and 3 is 15.
Amount that Abi spent less than Cole
= 10 u - 3 u
= 7 u
7 u = 1890
1 u = 1890 ÷ 7 = 270
Amount that each of them had at first
= 15 u
= 15 x 270
= $4050
Answer(s): $4050
