Question

WRITE an equation for each situation and solve. Define your variable and make sure your solutions have units.

A computer repair bill was $180. This included $45 for parts and $45 for each hour of labor. Find the number of hours of labor.
PLEASE HELP!

Answer 1

45 + 45x = 180

subtract 45 from both sides :

45x = 135

divide by 45 to get x by itself :

x = 3

Your answers are :

45 + 45x = 180

and

x = 3

Answer 2

33 3/4 hours or 33 hours and 45 minutes

Explanation:

Let h=hours

180=45+45h

Solving for h...

135=45h

h=33.75 or 33 hours and 45 minutes
