The graph represents a mechanic’s labor costs for a given number of hours of car repair. Which statement describes the relationship between labor cost and time for a car repair?

Answer 1

For the 1st hour the cost is $50 whatever is the duration (providing it's 1 hour max.

From one hour and onward the cost becomes an additional $25 per quater of an hour.

If y is the cost and x the number of hours, then the equation becomes :

y =50 + 0.25.x or y =1/4x + 50
