For 2014, Bakers Manufacturing uses machine-hours as the only overhead cost-allocation base. The direct cost rate is $3.00 per unit. The selling price of the product is $20.00. The estimated manufacturing overhead costs are $240,000 and estimated 40,000 machine hours. The actual manufacturing overhead costs are $300,000 and actual machine hours are 50,000 hours.

Using normal costing, what is the 2014 indirect cost rate? (HINT: Answer is $6.00 per machine-hour, but I need work to support this)
