Question

a. $49.00
b. $67.00
c. $85.00
d. $103.00

Answer 1

The total cost for a 4-hour cleaning job is $85.00, calculated by adding the initial charge of $49.00 to the additional charge of $36.00 for 2 extra hours beyond the initial 2-hour period.

Step-by-step explanation:

The total cost for a cleaning job that took 4 hours to complete can be calculated by combining the initial service charge with the additional hourly fees for the hours worked beyond the initial 2-hour period.

The initial service charge is $49.00 for the first 2 hours. Since the job took 4 hours, which is 2 hours longer than the initial period, the additional hours charge comes into play. For each additional hour, the service charges $18.00.

Thus, the additional charge for 2 extra hours is:

Adding this to the initial charge gives the total cost:

Therefore, the total cost for the cleaning service is $85.00, which corresponds to option c.
