34 of his pay and Luis saved
25 of his pay. Lee saved $140 more than Luis in a month. How much did Luis save in a month?

Lee |
Luis |
Before |
4x5 = 20 u |
5x4 = 20 u |
Change |
- 3x5 = - 15 u |
- 2x4 = - 8 u |
After |
1x5 = 5 u |
3x4 = 12 u |
The amount that Lee and Luis each earned in a month is the same. Make the amount the same. LCM of 4 and 5 is 20.
Amount that Lee saved more than Luis
= 15 u - 8 u
= 7 u
7 u = 140
1 u = 140 ÷ 7 = 140
Amount that Luis saved in a month
= 8 u
= 8 x 140
= $1120
Answer(s): $1120
