The total bill for repairing Steve's television was $125. The
repair shop charged $25 an hour for labor plus $19 for parts.
How many hours of labor did it take to repair Steve's television?
Round the answer to the nearest tenth of an hour.
A 4.2 hours
B 5.0 hours
C 5.3 hours
D 7.9 hours

Let’s make an equation
$25 would be the slope (rate of change)
$19 would be “one time fee” (y intercept)
Slope intercept formula: y = mx + b
Plug the values in (y = total cost)
$125 = $25x + $19
Solve for x, hours
$106 = $25x, x = 4.25
Nearest tenth = 4.2

Solution: A. 4.2 hours
