23 of his pay and Seth saved
27 of his pay. Brandon saved $150 more than Seth in a month. How much did Seth save in a month?

Brandon |
Seth |
Before |
3x7 = 21 u |
7x3 = 21 u |
Change |
- 2x7 = - 14 u |
- 2x3 = - 6 u |
After |
1x7 = 7 u |
5x3 = 15 u |
The amount that Brandon and Seth each earned in a month is the same. Make the amount the same. LCM of 3 and 7 is 21.
Amount that Brandon saved more than Seth
= 14 u - 6 u
= 8 u
8 u = 150
1 u = 150 ÷ 8 = 150
Amount that Seth saved in a month
= 6 u
= 6 x 150
= $900
Answer(s): $900
