The total cost of repair of the computer, includes the cost of replacement parts and labor
The general form of the equation that can be used to determine <em>x</em> is presented as follows; <u>C = p + t·x</u>
Where;
C = Total cost = $320.25
p = The cost of parts = $114
t = The time = 2.75 hours
- The equation that can be used to determine <em>x</em> is; <u>320.25 = 114 + 2.75·x</u>
- Cost of labor per hour is <u>$75</u>
Reason:
The known parameter for the cost of the repair are;
The time it took the technician at the store to work on the computer, t = 2.75 hours
The amount the technician charged for the parts, p = $114
The total cost of the repair, C = $320.25
Required:
Write and solve an equation which can be used to determine <em>x</em>, the Cost of labor per hour
By observation, we have;
The total cost, C = p + t × x
C = 320.25
p = 114
t = 2.75
The equation that can be used to determine <em>x</em>, is therefore;
- <u>320.25 = 114 + 2.75·x</u>
Solving, we get;
Cost of labor per hour, x = <u>$75</u>
