Can someone explain to me how to find the following:

Russel Company is a consulting firm. The firm expects to have $56,800 in indirect costs during the year and bill customers for 8,000 hours. The cost of direct labor is $70 per hour.

16.Calculate the predetermined overhead allocation rate for Russel using estimated billable hours for the allocation base.

17.Russel completed a consulting job for Ethan Murphy and billed the customer for 16 hours. What was the total cost of the consultingjob?

18.If Russel wants to earn a profit equal to 70% of the cost of ajob, how much should the company charge Mr.Murphy
