Show me the steps to solve Roberts Company produces two weed eaters: basic and advanced. The company has four activities: machining, engineering, receiving, and inspection. Information on these activities and their drivers is given below.

Basic Advanced Total

Units produced $120,000360,000$

Prime costs $$10,560,000$ $$36,720,000$ $$47,280,000$

Machine hours $120,000600,000720,000$

Engineering hours $2001,8002,000$

Receiving orders $3009001,200$

Inspection hours $8001,6002,400$

Overhead costs:

Machining $$7,920,000$

Engineering $940,000$

Receiving $408,000$

Inspecting products $480,000$

Required:

$1.$ Calculate the four activity rates.

Machining rate $fill in the blank $1$

$11$

per machine hour

Engineering rate $fill in the blank $2$

$470$

per hour

Receiving rate $fill in the blank $3$

$340$

per order

Inspecting rate $fill in the blank $4$

$200$

per hour

$2.$ Calculate the unit costs using activity rates. Round your answers to the nearest cent.

Unit cost

Basic $fill in the blank $5$

per unit

Advanced $fill in the blank $6$

per unit

Calculate the overhead cost per unit. Round your answers to the nearest cent.

Overhead Cost

Basic $fill in the blank $7$
