Comparing Jean and Natalie at first |
5x6 = 30 u |
7x6 = 42 u |
Before |
6x5 = 30 u |
|
Change |
- 5x5 = - 25 u |
|
After |
1x5 = 5 u |
42 u |
Comparing Jean and Natalie in the end |
|
$740 less |
Jean's salary at first is repeated. Make Jean's salary at first the same. LCM of 5 and 6 is 30.
Amount that Jean will have less than Natalie in the end
= 42 u - 5 u
= 37 u
37 u = 740
1 u = 740 ÷ 37 = 20
Natalie's salary
= 42 u
= 42 x 20
= $840
Answer(s): $840
