Carl and Ian earned the same amount each month. Carl saved
58 of his pay and Ian saved
25 of his pay. Carl saved $30 more than Ian in a month. How much did Ian save in a month?

Carl |
Ian |
Before |
8x5 = 40 u |
5x8 = 40 u |
Change |
- 5x5 = - 25 u |
- 2x8 = - 16 u |
After |
3x5 = 15 u |
3x8 = 24 u |
The amount that Carl and Ian each earned in a month is the same. Make the amount the same. LCM of 8 and 5 is 40.
Amount that Carl saved more than Ian
= 25 u - 16 u
= 9 u
9 u = 30
1 u = 30 ÷ 9 = 30
Amount that Ian saved in a month
= 16 u
= 16 x 30
= $480
Answer(s): $480
