Question

Saxbury Corporation's relevant range of activity is 3,000 units to 7,000 units. When it produces and sells 4,500 units, its average costs per unit are as follows:

	Average Cost per Unit
Direct materials	$	6.30
Direct labor	$	3.20
Variable manufacturing overhead	$	1.90
Fixed manufacturing overhead	$	3.90
Fixed selling expense	$	0.85
Fixed administrative expense	$	0.70
Sales commissions	$	0.60
Variable administrative expense	$	0.60

Required:

a. For financial reporting purposes, what is the total amount of product costs incurred to make 4,500 units?

b. For financial reporting purposes, what is the total amount of period costs incurred to sell 4,500 units?

c. If 5,500 units are sold, what is the variable cost per unit sold? (Round "Per unit" answer to 2 decimal places.)

d. If 5,500 units are sold, what is the total amount of variable costs related to the units sold?

e. If 5,500 units are produced, what is the average fixed manufacturing cost per unit produced? (Round "Per unit" answer to 2 decimal places.)

f. If 5,500 units are produced, what is the total amount of fixed manufacturing cost incurred?

g. If 5,500 units are produced, what is the total amount of manufacturing overhead cost incurred? What is this total amount expressed on a per unit basis? (Round "Per unit" answer to 2 decimal places.)

h. If the selling price is $23.80 per unit, what is the contribution margin per unit sold? (Round "Per unit" answer to 2 decimal places.)

i. If 3,500 units are produced, what is the total amount of direct manufacturing cost incurred?

j. If 3,500 units are produced, what is the total amount of indirect manufacturing cost incurred?

k. What incremental manufacturing cost will the company incur if it increases production from 4,500 to 4,501 units? (Round "Per unit" answer to 2 decimal places.)

Answer 1

a) Total product cost = 15.30*4500 = $68850

b) Total period cost = 2.75*4500 = $12375

c) Variable cost per unit sold = $12.60

d) Total Variable cost = 5500*12.60 = $69300

e) Average Fixed manufacturing cost per unit = (4500*3.9)/5500 = 3.19

f) Total amount of fixed manufacturing overhead = 4500*3.9 = 17550

g) Total amount of manufacturing cost = (5500*11.40+4500*3.9) = 80250

Per unit = 80250/5500 = 14.59

h) Contribution margin per unit = 23.80-12.60 = 11.20

i) Direct manufacturing cost = 3500*11.40 = 39900

j) Indirect manufacturing cost = 17550

k) Incremental cost = $11.40
