Answer:
3 hours
Step-by-step explanation:
Let
x ----> the number of hours
y ----> the total cost per repair the computer
we know that
The total cost per repair the computer is equal to the cost of the parts plus the number of hours it take to repair the computer multiplied by $45 per hour
so
The linear equation that represent this problem is
[tex]y=45x+44[/tex]
For y=$179
substitute in the linear equation and solve for x
[tex]179=45x+44[/tex]
[tex]45x=179-44[/tex]
[tex]45x=135[/tex]
[tex]x=3\ hours[/tex]
