37 of his pay. Reggie saved $90 more than George in a month. How much did George save in a month?

George |
Before |
3x7 = 21 u |
7x3 = 21 u |
Change |
- 2x7 = - 14 u |
- 3x3 = - 9 u |
After |
1x7 = 7 u |
4x3 = 12 u |
The amount that Reggie and George each earned in a month is the same. Make the amount the same. LCM of 3 and 7 is 21.
Amount that Reggie saved more than George
= 14 u - 9 u
= 5 u
5 u = 90
1 u = 90 ÷ 5 = 90
Amount that George saved in a month
= 9 u
= 9 x 90
= $810
Answer(s): $810
