When a homeowner hires a contractor to renovate a bathroom, the homeowner is charged for both labor and materials. By law, the contractor can charge sales tax on the materials, but not on the labor. If the contractor quotes the homeowner $3,000 for materials and $40 per hour for labor, and sales tax in the homeowner's state is 5.5%, which equation represents the total cost for the bathroom renovation if it takes the contractor h hours to complete the job?
A. c = (40h + 3,000)(1.055)
B. c = 1.055(40 + 3,000)h
C. c = 40h(1.055) + 3,000
D. c = 40h + 1.055(3,000)
