Seth and Oscar earned the same amount each month. Seth saved
35 of his pay and Oscar saved
27 of his pay. Seth saved $190 more than Oscar in a month. How much did Oscar save in a month?
|
Seth |
Oscar |
Before |
5x7 = 35 u |
7x5 = 35 u |
Change |
- 3x7 = - 21 u |
- 2x5 = - 10 u |
After |
2x7 = 14 u |
5x5 = 25 u |
The amount that Seth and Oscar each earned in a month is the same. Make the amount the same. LCM of 5 and 7 is 35.
Amount that Seth saved more than Oscar
= 21 u - 10 u
= 11 u
11 u = 190
1 u = 190 ÷ 11 = 190
Amount that Oscar saved in a month
= 10 u
= 10 x 190
= $1900
Answer(s): $1900
