37 of his pay. Zeph saved $80 more than Luke in a month. How much did Luke save in a month?

Zeph |
Luke |
Before |
4x7 = 28 u |
7x4 = 28 u |
Change |
- 3x7 = - 21 u |
- 3x4 = - 12 u |
After |
1x7 = 7 u |
4x4 = 16 u |
The amount that Zeph and Luke each earned in a month is the same. Make the amount the same. LCM of 4 and 7 is 28.
Amount that Zeph saved more than Luke
= 21 u - 12 u
= 9 u
9 u = 80
1 u = 80 ÷ 9 = 80
Amount that Luke saved in a month
= 12 u
= 12 x 80
= $960
Answer(s): $960
