Calculate the four activity rates. Machining rate $ per machine hour Engineering rate $ per hour Receiving rate per order Inspecting rate per hour 2. Calculate the unit costs using activity rates. Round your answers to the nearest cent. Unit cost Basic per unit Advanced $ per unit Calculate the overhead cost per unit. Round your answers to the nearest cent. Overhead Cost Basic $ per unit Advanced $ per unit 3. If consumption ratios instead of activity rates were used to assign costs instead of activity rates, show the cost assignment for the inspection activity. Cost assignment Basic Advanced
