Solve the problem.To remodel a bathroom, a contractor charges $25 per hour plus material costs, which amount to $3,775. 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) = - 3,775; This computes the number of hours worked if the total cost is x dollars.
B. f -1(x) = - 151; This computes the total cost if the contractor works x hours.
C. f -1(x) = - 151; This computes the number of hours worked if the total cost is x dollars.
D. f -1(x) = - 3,775; This computes the total cost if the contractor works x hours.
