Solve the problem.To remodel a bathroom, a contractor charges $25 per hour plus material costs, which amount to $3825. Therefore, the total cost to remodel the bathroom is given by 
where x is the number of hours the contractor works. Find a formula for 
What does 
compute?
A. f -1(x) = 
- 3825; This computes the total cost if the contractor works x hours.
B. f -1(x) = 
- 153; This computes the total cost if the contractor works x hours.
C. f -1(x) = 
- 153; This computes the number of hours worked if the total cost is x dollars.
D. f -1(x) = 
- 3825; This computes the number of hours worked if the total cost is x dollars.
