Question
1. Using the data in Exhibit 2 calculate the cost function (y=mx + b) using the high-low method a. Note there are only 22 data
1. Using the data in Exhibit 2 calculate the cost function (y=mx + b) using the high-low method
a. Note there are only 22 data points (August and September of the 2nd year are missing)
b. Be sure to check for outliers in the data prior to choosing your high-low points
2. Using the data in Exhibit 4 calculate the per-unit cost for each of the categories, then identify each cost as fixed, variable or mixed
a. Note Calculating the per-unit cost helps to identify costs as fixed, variable or mixed

b. Create a chart which identifies the fixed and variable costs. Remember that mixed costs need to be converted to their fixed and variable portions using the high-low method. This chart should then give you an updated cost function (y=mx +b). This updated cost function is used in questions 4 and 5 below.

3. For each cost listed in Exhibit 3, indicate whether the cost is a manufacturing or nonmanufacturing cost.
4. Using the cost equation, you developed in Question 2.b. answer the following:
a. Assume the company expects to produce and sell 1,500 units during the following month at a price of $100 per unit:
i. Prepare an income statement based on financial reporting (absorption method)
ii. Prepare an income statement based on the contribution margin approach (variable method)
iii. Calculate the contribution margin per unit
iv. Calculate the break-even point in units per month
5. The owners have set a target profit of $25,000 per month ($300,000 per year) in order from them to devote themselves full-time to JW Sports Supplies. Evaluate each of the following factors, separately (assume other factors stay the same as in the income statement from number 4 above):
a. What price must the company set to achieve a profit of $25,000?
b. What must the variable cost per unit be to achieve a profit of $25,000?
c. How many units must it sell to achieve a profit of $25,000?
d. What must total monthly fixed costs be to achieve a profit of $25,000?
