Question

An emergency plumber charges $49.00 plus $70.00 per hour of the repair. A bill to repair your sink is $241.50. This can be modeled by $70.00h+49.00=241.50$, where h represents the number of hours for the repair. How many hours did it take to repair your sink?

• A. 2.75 hours
• B. 3.45 hours
• C. 4.15 hours
• D. 13,475 hours

Answer 1

The correct option is A

2.75 hours

Given,

$$\begin{gathered} 70.00h+49.00=241.50 \\ 70h=241.50–49 \\ 70h=192.5 \\ h=2.75hours \end{gathered}$$

Thus, the correct option is option A.
