Solve the problem.To remodel a bathroom, a contractor charges $25 per hour plus material costs, which amount to $3700. 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) =  - 3700; This computes the number of hours worked if the total cost is x dollars.
B. f^-1(x) =  - 148; This computes the number of hours worked if the total cost is x dollars.
C. f^-1(x) =  - 148; This computes the total cost if the contractor works x hours.
D. f^-1(x) =  - 3700; This computes the total cost if the contractor works x hours.
