- 2x3 = - 6 u |
|
After |
3x3 = 9 u |
35 u |
Comparing Ivory and Min in the end |
|
$2080 more |
Ivory's salary at first is repeated. Make Ivory's salary at first the same. LCM of 3 and 5 is 15.
Amount that Min will have more than Ivory in the end
= 35 u - 9 u
= 26 u
26 u = 2080
1 u = 2080 ÷ 26 = 80
Ivory's salary
= 15 u
= 15 x 80
= $1200
Answer(s): $1200
