Answer:

$65/hour

Step-by-step explanation:

Let C(h) represent the total amount payable to the plumber. Then:

C(h) = $75 + (rate)(2 hr) = $205. Solve for the "fixed hourly rate."

Subtracting $75 from both sides, we get:

(rate)(2 hr) = $130.

Dividing both sides by (2 hr) results in (rate) = $65/hour

Step-by-step explanation:
