Kevin painted
of the wall.
Solution:
Fraction of the wall painted by Elena =

You will have to get the difference and get a common denominator but first combine the mixed number:

Then subtract the numbers

Angel took 5/12 hours longer than Chris
I = Prt
P = i / rt
P = 288 / (0.016 * 3)
P = 288 / 0.048
P = 6,000
answer
He should deposit $6,000
