D=57 and r=30, then by the formula d=r*t
57=30*t.
dividing 30 on both sides we get, t= 57/30
t=1.9
The food bill would be $100.24
The final bill is $544
The parts is a one time bill of $265
The labor is $48 per hour, and lets call the hours 'h'
So we can make the equation as:
544 = 265 + 48h
Subtract 265 n both sides
279 = 48h
Divide by 48 on both sides
h = <span>5.8125
So the number of hours of labor spent repairing the car is </span><span>5.8125.</span>
