TB Problem $4-121($Algo$)$ Walnut Systems produces two products...

Walnut Systems produces two products, Product A$,$ which sells for $$121$ per unit, and Product B$,$ which sells for $$208$ per unit, using three activities: Design, which uses engineering hours as the cost driver; Machining, which uses machine hours as the cost driver; and Inspection, which uses the number of batches as the cost driver. The cost of each activity and usage of the cost drivers are as follows:

$\backslash$table$[[$Activity Pool $($Driver$),$Cost of Pool,Usage by Product A$,$Usage by Product B$],[$Design $($Engineering Hours$),$$$165,375,212,313],[$Machining $($Machine Hours$),567,180,1,140,3,000],[$Inspection $($Batches$),28,670,38,23]]$

Walnut manufactures $10,300$ units of Product A and $6,800$ units of Product B per month. Each unit of Product A uses $$45$ of direct materials and $$20$ of direct labor, while each unit of Product $B$ uses $$75$ of direct materials and $$34$ of direct labor.

Required:

a$.$ Calculate the activity rate for design.

b$.$ Calculate the activity rate for machining.

c$.$ Calculate the activity rate for inspection.

d$.$ Determine the indirect costs assigned to Product A$.$

e$.$ Determine the indirect costs assigned to Product B$.$

f$.$ Determine the manufacturing cost per unit for Product $A.$

Note: Round your answer to $2$ decimal places.

g$.$ Determine the manufacturing cost per unit for Product B$.$

Note: Round your answer to $2$ decimal places.

h$.$ Determine the gross profit per unit for Product $A.$

Note: Round your intermediate calculation to $2$ decimal places. Round your answer to $2$ decimal places.

i$.$ Determine the gross profit per unit for Product B$.$
