Gwen and Ian had the same amount of savings at first. Then Gwen spent
16 of her savings and Ian spent
45 of his savings. If Gwen spent $1691 less than Ian, how much did each of them have at first?
| |
Gwen |
Ian |
| Before |
6x5 =
30 u |
5x6 =
30 u |
| Change |
1x5 =
- 5 u |
4x6 =
- 24 u |
| After |
25 u |
6 u |
The amount that Gwen and Ian had at first is the same. Make the amount that Gwen and Ian each had the same. LCM of 6 and 5 is 30.
Amount that Gwen spent less than Ian
= 24 u - 5 u
= 19 u
19 u = 1691
1 u = 1691 ÷ 19 = 89
Amount that each of them had at first
= 30 u
= 30 x 89
= $2670
Answer(s): $2670
