Eva and Billy had the same amount of savings at first. Then Eva spent
15 of her savings and Billy spent
23 of his savings. If Eva spent $539 less than Billy, how much did each of them have at first?
| |
Eva |
Billy |
| Before |
5x3 =
15 u |
3x5 =
15 u |
| Change |
1x3 =
- 3 u |
2x5 =
- 10 u |
| After |
12 u |
5 u |
The amount that Eva and Billy had at first is the same. Make the amount that Eva and Billy each had the same. LCM of 5 and 3 is 15.
Amount that Eva spent less than Billy
= 10 u - 3 u
= 7 u
7 u = 539
1 u = 539 ÷ 7 = 77
Amount that each of them had at first
= 15 u
= 15 x 77
= $1155
Answer(s): $1155
