Absolutely lost. I have no idea how to do the workings of these.

Major Instrument, Inc. manufactures two products: missile range instruments and space pressure gauges. During April, 48 range instruments and 298 pressure gauges were produced, and overhead costs of $89, 301 were estimated. An analysis of estimated overhead costs reveals the following activities. The cost driver volume for each product was as follows. Determine the overhead rate for each activity. Assign the manufacturing overhead costs for April to the two products using activity-based costing. (Round cost per unit to 2 decimal places, e.g. $120.25 and total cost assigned to 0 decimal places, e.g. $2, 500.)
