Gwen and Ryan had the same amount of savings at first. Then Gwen spent
14 of her savings and Ryan spent
45 of his savings. If Gwen spent $1320 less than Ryan, how much did each of them have at first?

Gwen |
Ryan |
| Before |
4x5 =
20 u |
5x4 =
20 u |
| Change |
1x5 =
- 5 u |
4x4 =
- 16 u |
| After |
15 u |
4 u |
The amount that Gwen and Ryan had at first is the same. Make the amount that Gwen and Ryan each had the same. LCM of 4 and 5 is 20.
Amount that Gwen spent less than Ryan
= 16 u - 5 u
= 11 u
11 u = 1320
1 u = 1320 ÷ 11 = 120
Amount that each of them had at first
= 20 u
= 20 x 120
= $2400
Answer(s): $2400
