Supervisor a earns a flat rate of $25 per hour, while supervisor b earns $20 per hour for the first 30 hours and then 50% more f
mixas84 [53]
Let same number of hours = x, 
since the salary earned is also the same, then
Salary of supervisor A = $25x
Salary of supervisor B = $20(30)+$30(x-30)
Equating
25x=600+30(x-30)
30x-25x=900-600
5x=300
x=60 hours
Check:
Salary of supervisor A = 25*60=1500
Salary of supervisor B =  20*30+30*(60-30)=600+900=1500, ok.

Why does the fraction 20/25 not belong with 1/20, 2/3 and 5/4?
devlian [24]
I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.
