Explanation:
National Corporation
M14–M16
                         Per Unit          Total
Direct materials               $23           1840,000
Direct labor                  $45          3600,000 Â
Variable manufacturing overhead $12 Â Â Â Â Â Â Â Â 960,000
Fixed manufacturing overhead              $1,296,000
Variable selling & Admin. Â expenses $ 10 Â Â Â Â Â 800,000
Fixed selling and administrative expenses     $ 1,134,000
Total Variable Costs  per unit $ 90
Direct materials $23
Direct labor $45
Variable manufacturing overhead $12
Variable selling & Admin. Â expenses $ 10
Total Fixed Cost per unit $ 30.375
Fixed manufacturing overhead  =$1,296,000/ 80,000=  $ 16.2
Fixed selling and administrative expenses  = $ 1,134,000 / 80,000 = $ 14.175
Total Unit Costs= Total Variable Costs  per unit + Total Fixed Cost per unit
             =$ 90 + $ 30.375= $ 120.375
Return on investment measures the benefit an investor will receive in relation to their investment cost.
Desired ROI per unit + Fixed Cost= Mark Up  Percentage * Variable Cost Per Unit
Putting values in the above
Desired ROI per unit + Â $ 30.375= 35 % * $ 90
Desired ROI per unit = 31.5- 30.375
Desired ROI per unit = $ 1.125= $ 1.13
The investor will receive a benefit of $ 1.13 per unit .
