MANUFACTURING PROCESSES chapter 6 201So if we can produce 100 units in 45 minutes, we need to calculate how many units can beproduced in 60 minutes. We can find this with the following ratio:Solving for XThe cost per unit is thenIf the batch size were increased to 200 units45 / 100 = 60 / XX = 133.3 units / hour$500 / 133.3 = $3.75 / unit5 + 10 + 0.2(200) + 0.1(200) = 15 + 60 = 75 minutes / 200 units75 / 200 = 60 / X X = 160 / hour $500 / 160 = $3.125 / unitOBJECTIVE QUESTIONS1. A book publisher has fixed costs of $300,000 and variable costs per book of $8.The book sells for $23 per copy.a. How many books must be sold to break even?b. If the fixed cost increased, would the new break-even point be higher or lower?c. If the variable cost per unit decreased, would the new break-even point behigher or lower?2. A manufacturing process has a fixed cost of $150,000 per month. Each unit ofproduct being produced contains $25 worth of material and takes $45 of labor. Howmany units are needed to break even if each completed unit has a value of $90?3. Assume a fixed cost of $900.00, a variable cost of $4.50, and a selling price of$5.50.a. What is the break-even point?b. How many units must be sold to make a profit of $500.00?c. How many units must be sold to average $0.25 profit per unit? $0.50 profit perunit? $1.50 profit per unit?4. Aldo Redondo drives his own car on company business. His employer reimburseshim for such travel at the rate of 36 cents per mile. Aldo estimates that his fixedcosts per year such as taxes, insurance, and depreciation are $2,052.00. The director variable costs such as gas, oil, and maintenance average about 14.4 cents permile. How many miles must he drive to break even?5. A firm is selling two products, chairs and bar stools, each at $50 per unit. Chairshave a variable cost of $25, and bar stools $20. Fixed cost for the firm is $20,000.a. If the sales mix is 1:1 (one chair sold for every bar stool sold), what is thebreak-even point in dollars of sales? In units of chairs and bar stools?b. If the sales mix changes to 1:4 (one chair sold for every four bar stools sold),what is the break-even point in dollars of sales? In units of chairs and bar stools?6. A firm is refilling printer ink cartridges for sale on the Internet. The annual fixedcost is $10,000.00 for this process, direct labor is $3.50 per package, and materialis $4.50 per package. The selling price will be $12.50 per package. How muchrevenue does the firm need to take in before breaking even? What is the breakevenpoint in units?
