Sales salaries and commissions are $10,000 when 80,000 units are sold, and $14,000 when 120,000 units are sold. Using the high-low method, what is the total fixed cost (the "a" in the cost line equation) portion of sales salaries and commissions? Hint: pick the high or the low and plug total cost (Y), total activity (X), and the "b" from the prior problem into: Y = a + bx. Solve for "a". $1,000 $2,000 O $10,000 $3,000 Coffee Klatch is an espresso stand in a downtown office building. The average selling price of a cup of coffee is $1.59 and the average variable expense per cup is $0.56. The average fixed expense per month is $1,450. 2,200 cups are sold each month on average. What is the CM Ratio for Coffee Klatch? Express as a percentage. Go to one decimal place (ex. 71.8%) Hint: you can calculate CM ratio by using total numbers or per unit numbers. I'd recommend per unit...it is easier. CM ratio = Total CM/Total Sales or Unit CM/Sales price per unit 35.2% 64.8% 71.1% 73.8%
