Luis and Elijah earned the same amount each month. Luis saved
23 of his pay and Elijah saved
27 of his pay. Luis saved $130 more than Elijah in a month. How much did Elijah save in a month?
|
Luis |
Elijah |
Before |
3x7 = 21 u |
7x3 = 21 u |
Change |
- 2x7 = - 14 u |
- 2x3 = - 6 u |
After |
1x7 = 7 u |
5x3 = 15 u |
The amount that Luis and Elijah each earned in a month is the same. Make the amount the same. LCM of 3 and 7 is 21.
Amount that Luis saved more than Elijah
= 14 u - 6 u
= 8 u
8 u = 130
1 u = 130 ÷ 8 = 130
Amount that Elijah saved in a month
= 6 u
= 6 x 130
= $780
Answer(s): $780
