Answer:
Josh makes $36 more per hour than Greg.
Step-by-step explanation:
First, you need to determine the amount Josh earns per hour as you know that it takes him 5 hours of work to save $480:
5x=480
Now, you can solve for x:
x=480/5
x=96
Then, you need to determine the amount Greg earns per hour as you know that it takes him 8 hours of work to save $480:
8y=480
Now, you can solve for y:
y=480/8
y=60
96-60=36
According to this, the answer is that Josh makes $36 more per hour than Greg.
L=w+4m
A=w*l
A=w(w+4)=45
w^2+4w-45=0
w^2+9w-5w-45=0
w(w+9)-5(w+9)=0
(w+9)(w-5)=0
⇒ w+9=0 or w-5=0
⇒w-5=0
w=5
l=5+4
l=9
