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.
