Archie and Japheth earned the same amount each month. Archie saved
23 of his pay and Japheth saved
27 of his pay. Archie saved $10 more than Japheth in a month. How much did Japheth save in a month?

Archie |
Japheth |
Before |
3x7 = 21 u |
7x3 = 21 u |
Change |
- 2x7 = - 14 u |
- 2x3 = - 6 u |
After |
1x7 = 7 u |
5x3 = 15 u |
The amount that Archie and Japheth each earned in a month is the same. Make the amount the same. LCM of 3 and 7 is 21.
Amount that Archie saved more than Japheth
= 14 u - 6 u
= 8 u
8 u = 10
1 u = 10 ÷ 8 = 10
Amount that Japheth saved in a month
= 6 u
= 6 x 10
= $60
Answer(s): $60
