Mr. Johnson hired a contractor to build a small deck on the back of his house. The cost of materials alone added to $678.12. When he received the final bill from the contractor, the total amount charged was $1206.12. Verify the accuracy of this bill if labor amounted to 16.5 hours at $32 an hour

Yes, the bill is absolutely accurate

Step-by-step explanation:

Cost of materials= $ 678.12

Final  bill amount(given)=$1206.12

Rate= $32 per hour for 16.5 hrs

Total amount for 32 hrs = time * rate = 16.5* 32=$528

Therefore, by the problem ,

Cost of materials+ Total amount  for 32 hrs = Final bill amount

= 678.12+ 528

=1206.12

Therefore , the final bill amount is 100% accurate as it completely matches with the given bill amount
