Explanation:

To calculate these, the following formula will be used the calculations:

a. Variable production cost per unit = Labor + Outsourced test + Materials used + Production

b. Variable cost per unit = Variable production cost + Selling and administration

c. Full cost per unit = Variable cost per unit + (Total fixed costs / Number of tests)

d. Full absorption cost per unit = Variable production cost per unit + (Production overhead / Number of tests)

e. Prime cost per unit = Material + Labor + Outsource test analysis

f. Conversion cost per unit = Labor + Outsource test + Variable production overhead+ (Fixed production overhead / Number of tests)

g. Contribution margin per unit = Sale price - Variable cost per unit

h. Gross margin per unit = Sale price - Full absorption cost

Therefore, we can now proceed as follows:

1. Calculate the amount for each of the following (one unit = one test) if the number of tests is 1,500 per month.

a. Variable production cost per unit = Labor + Outsourced test + Materials used + Production = 360 + 60 + 15 + 30 = 465 per unit

b. Variable cost per unit = Variable production cost + Selling and administration per unit = 465 + 45 = 510 per unit

c. Full cost per unit = Variable cost per unit + (Total fixed costs / Number of tests) = 510 + ((90,000 + 135,000) / 1,500) = 510 + (225,000 / 1,500) = 510 + 150 = 660 per unit

d. Full absorption cost per unit = Variable production cost per unit + (Fixed production overhead / Number of tests) = 465 + (135,000 / 1,500) = 465 + 90 = 555 per unit

e. Prime cost per unit = Material + Labor + Outsource test analysis = 15 + 360 + 60 = 435 per unit

f. Conversion cost per unit = Labor + Outsource test + Variable production overhead + (Fixed production overhead / Number of tests) = 360 + 60 + 30 + (135,000 / 1,500) = 360 + 60 + 30 + 90 = 540 per unit

g. Contribution margin per unit = Sale price - Variable cost per unit = 900 – 510 = 390 per unit

h. Gross margin per unit = Sale price per unit - Full absorption cost per unit = 900 – 555 = 345

2. Also calculate if the number of tests decreases to 1,250 per month.

a. Variable production cost per unit = Labor + Outsourced test + Materials used + Production = 360 + 60 + 15 + 30 = 465 per unit

b. Variable cost per unit = Variable production cost + Selling and administration per unit = 465 + 45 = 510 per unit

c. Full cost per unit = Variable cost per unit + (Total fixed costs / Number of tests) = 510 + ((90,000 + 135,000) / 1,250) = 510 + (225,000 / 1,250) = 510 + 180 = 690 per unit

d. Full absorption cost per unit = Variable production cost per unit + (Fixed production overhead / Number of tests) = 465 + (135,000 / 1,250) = 465 + 108 = 573 per unit

e. Prime cost per unit = Material + Labor + Outsource test analysis = 15 + 360 + 60 = 435 per unit

f. Conversion cost per unit = Labor + Outsource test + Variable production overhead + (Fixed production overhead / Number of tests) = 360 + 60 + 30 + (135,000 / 1,250) = 360 + 60 + 30 + 108 = 558 per unit

g. Contribution margin per unit = Sale price - Variable cost per unit = 900 – 510 = 390 per unit

h. Gross margin per unit = Sale price per unit - Full absorption cost per unit = 900 – 573 = 327
