Hi. The gcf of 60 and 72 is 12. Hope that helps!
72/12=6
60/12=5
Start by multiplying 1.2 and 7.5 which will give you 9.Then you have 9-8/4. so then you do 8 divided by 4 which is 2. so you have 9-2 and that equals 7.
buy = 30 share at 20 1/4 each
sell = 30 share at 25 1/4
profit $5 share profit
total profit is 150$
