Answer and Explanation:

According to the scenario, computation of the given data are as follow:-

Total Unit Cost of Making Product = Direct Material + Direct Labor + Variable Overhead + Fixed Overhead

= $53 + $40 + $36 + $31

= $160

Total Unit Cost of Buying Product = Fixed Cost + Purchase Cost

= $31 + $145

= $176

Particular Make product($) Buy product($)

Direct material(7,000 × $53) 371,000 -

Direct labor(7,000 × $40) 280,000 -

Variable overhead(7,000 ×$36) 252,000 -

Fixed overhead(7,000 × $31) 217,000 132,000

(217,000 - 85,000)

Purchase cost 7,000 × $145 = 1,015,000

Total cost 1,120,000 1,147,000

Difference between two alternatives

= $1,147,000 - $1,120,000

= $27,000

According to the analysis, rubium make the product because buying product cost is more than making the product.
