Question

Kevin needs to have a toilet Kevin needs to have a toilet repaired in his house. The cost of the new plumbing fixtures is $160 and the labor is $50/hr.(a) Write a model that represents the cost of the repair C (in $) in terms of the number of hours of labor x.

Answer 1

Given that:

Cost of the new plumbing fixtures = $160

Labor charge per hour = $50

Let x denotes the number of hours of labor. Then,

`\begin{gathered} \text{Cost of repair = Cost of the new plumbing fixtures+Labor charge per } \\ \text{hour}\cdot Number\text{ of hours of labor} \\ C=160+50x \end{gathered}`

It represents the required relation.
