Gillian and Fabian had the same amount of savings at first. Then Gillian spent
17 of her savings and Fabian spent
45 of his savings. If Gillian spent $1403 less than Fabian, how much did each of them have at first?

Gillian |
Fabian |
| Before |
7x5 =
35 u |
5x7 =
35 u |
| Change |
1x5 =
- 5 u |
4x7 =
- 28 u |
| After |
30 u |
7 u |
The amount that Gillian and Fabian had at first is the same. Make the amount that Gillian and Fabian each had the same. LCM of 7 and 5 is 35.
Amount that Gillian spent less than Fabian
= 28 u - 5 u
= 23 u
23 u = 1403
1 u = 1403 ÷ 23 = 61
Amount that each of them had at first
= 35 u
= 35 x 61
= $2135
Answer(s): $2135
