Question

find the relationship between the number of hours the mechanic works, h, and the total cost, v, for
a) v = 200
b) v = 200 + 45
h) v = 200 - 200
43.

Explanation:

Step1: Identify cost components

The total cost has a fixed $200 fee plus $45 per hour of work. Let $x$ = hours worked, $y$ = total cost.

Step2: Build the cost equation

Total cost = fixed cost + (hourly rate × hours), so $y = 45x + 200$.

Answer:

$y = 45x + 200$
