Answer:
$60
Step-by-step explanation:
Let the work done by Mary, John and Stacy be 3x,6x and 9x.
ATQ,
3x+6x+9x=360
18x = 360
x = 20
Mary's amount = 3x = 3(20) = $60
John's amount = 6x = 6(20) = $120
Stacy amount = 9x = 9(20) = $180
Difference in amont of Stacy and John = $180-$120 = $60
Hence, Stacy make $60 more than John's amount.
