Pls. read the attached file (The Minnetonka Corporation) and answer the following questions (The answers without considering the specific steps are also attached as "incomplete answers"):
* Pls. note that the "incomplete answers" are correct answers. I need more detailed answers following the steps. Thank you.

What is cost of making bindings internally?
STEPS
a. Separate the cost of making skis and making bindings.

Example: Material: \$30 total * 20% for bindings = \$ 6.00 for material for pair of bindings.
Do for Material, Labor, Variable Overhead. Total is avoidable cost to make bindings at Minnetonka.

b. Overhead: Total (variable and fixed) is \$15 per pair. You have to figure out the Fixed overhead per unit (\$100,000 total) and then take that out of the \$15 so you are left with only variable. You are only concerned with the VARIABLE part of the overhead (as this the avoidable cost for not making the bindings).

c. Total the Material, Labor, Overhead variable costs per unit.

2. What would be the maximum purchase price acceptable to the Minnetonka Corporation for the bindings? Support your answer with an appropriate explanation and you must follow the steps to answer:

You are only concerned with the VARIABLE part of the overhead (as this the avoidable cost for not making the bindings).

c. Total the Material, Labor, Overhead variable costs per unit.

3. Instead of sales of 10,000 pair of skis, revised estimates show sales volume at 12,500 pair. At this new volume, additional equipment, at an annual rental of \$10,000 must be acquired to manufacture the bindings. This incremental cost would be the only additional fixed cost required even if sales increased to 30,000 pair. (This 30,000 level is the goal for the third year of production.) Under these circumstances, should the Minnetonka Corporation make or buy the bindings? Show calculations to support your answer. You must follow the steps to answer:

At a volume of 12,500 pair, should Minnetonka buy the bindings?
STEPS
a. Compute total \$ cost of making (per unit variable plus fixed overhead) for 12,500 pair.

b. Compute total \$ cost of buying the bindings.

c. Compare the two.

d. Figure the units where making is better than buying (you could use algebra or just trial and error to find the point where it is cheaper to make vs. buy).

4. What nonquantifiable factors should the Minnetonka Corporation consider in determining whether they should make or buy the bindings? you must follow the steps to answer:

There are many nonquantifiable factors that Minnetonka should consider in addition to the economic factors calculated above.
STEPS
List 2 to 3 factors.
- Describe each performance system.
- Compare and contrast them.
- Bullet points and a table of compare and contrast.

The answers are in the attached file. Please note the the incomplete answers were NOT CORRECT, since the overhead was not broken into fixed and variable as was required by the Steps. The answers are not the same.

What is cost of making bindings internally?
STEPS
a. Separate the cost of making skis and making bindings.

Example: Material: \$30 total * 20% for bindings = \$ 6.00 for material for pair of bindings.
Do for Material, Labor, Variable Overhead. Total is avoidable cost to make bindings at Minnetonka.

Material is 20% of direct material cost = 30 X 20% = \$6 ( Direct material is given as \$30)
Direct Labor is 10% of Direct Labor Cost = 35 X 10% = \$3.50 ( Direct Labor is given as \$30)

b. Overhead: Total (variable and fixed) is \$15 per pair. You have to figure out the Fixed overhead per unit (\$100,000 total) and then take that out of the \$15 so you are left with only variable. You are only concerned with the VARIABLE part of the overhead (as this the avoidable cost for not making the bindings).

Total fixed overhead is \$100,000 and the total number of units is 10,000. The fixed overhead per unit is 100,000/10,000=\$10. Total overhead per unit is \$15. The variable overhead per unit is 15-10=\$5. The variable overhead for a pair of ...
