Seth and Justin earned the same amount each month. Seth saved
56 of his pay and Justin saved
25 of his pay. Seth saved $90 more than Justin in a month. How much did Justin save in a month?

Seth |
Justin |
Before |
6x5 = 30 u |
5x6 = 30 u |
Change |
- 5x5 = - 25 u |
- 2x6 = - 12 u |
After |
1x5 = 5 u |
3x6 = 18 u |
The amount that Seth and Justin each earned in a month is the same. Make the amount the same. LCM of 6 and 5 is 30.
Amount that Seth saved more than Justin
= 25 u - 12 u
= 13 u
13 u = 90
1 u = 90 ÷ 13 = 90
Amount that Justin saved in a month
= 12 u
= 12 x 90
= $1080
Answer(s): $1080
