Kylie and Japheth had the same amount of savings at first. Then Kylie spent
17 of her savings and Japheth spent
34 of his savings. If Kylie spent $1122 less than Japheth, how much did each of them have at first?
| |
Kylie |
Japheth |
| Before |
7x4 =
28 u |
4x7 =
28 u |
| Change |
1x4 =
- 4 u |
3x7 =
- 21 u |
| After |
24 u |
7 u |
The amount that Kylie and Japheth had at first is the same. Make the amount that Kylie and Japheth each had the same. LCM of 7 and 4 is 28.
Amount that Kylie spent less than Japheth
= 21 u - 4 u
= 17 u
17 u = 1122
1 u = 1122 ÷ 17 = 66
Amount that each of them had at first
= 28 u
= 28 x 66
= $1848
Answer(s): $1848
