Exercise 7–1
1. Total expected costs of the Maintenance Department:

Fixed costs $57,200 Variable costs ($0.75 × 22,000 maintenance hrs.) 16,500 Total costs $73,700

Single charging rate = $73,700/22,000 = $3.35 per maintenance hour

2. Charge based on actual usage = Charging rate × Actual maintenance hours

Assembly Department charge = $3.35 × 3,960 = $13,266 Fabricating Department charge = $3.35 × 6,800 = $22,780 Packaging Department charge = $3.35 × 10,000 = $33,500

Total amount charged = $13,266 + $22,780 + $33,500 = $69,546

3. Assembly Department charge = $3.35 × 4,000 = $13,400 Fabricating Department charge = $3.35 × 6,800 = $22,780 Packaging Department charge = $3.35 × 10,000 = $33,500

Total amount charged = $13,400 + $22,780 + $33,500 = $69,680

Exercise 7–8 1. Number Weight Weighted Number Allocated Grades of Pounds Factor of Pounds Percent Joint Cost

Grade A 1,500 3.0 4,500 0.1875 $1,125 Grade B 5,000 2.0 10,000 0.4167 2,500 Slices 8,000 0.5 4,000 0.1667 1,000 Applesauce 5,500 1.0 5,500 0.2292 1,375 Total 24,000 $6,000 2. If the Grade A weight factor is decreased to 2.0, then the weighted number of pounds would decrease by one-third and the Grade A apples would receive a relatively smaller amount of joint cost. However, the allocation of cost to all other grades will increase since the decreased weighted pounds for Grade A apples will impact all percentages. The following table shows what would happen:

Number Weight Weighted Number Allocated Grades of Pounds Factor of Pounds Percent Joint Cost

Grade A 1,500 2.0 3,000 0.1333 $ 800 Grade B 5,000 2.0 10,000 0.4444 2,666 Slices 8,000 0.5 4,000 0.1778 1,067 Applesauce 5,500 1.0 5,500 0.2444 1,467 Total 22,500 $6,000 *Adjust the $6,000 for rounding
Exercise 7–11
1. Total revenue: L-Ten ($2 × 3,500) $ 7,000 Triol ($5 × 4,000) 20,000 Pioze ($6 × 2,500) 15,000 $ 42,000 Further processing costs: L-Ten ($0.50 × 3,500) $ 1,750 Triol ($1.00 × 4,000) 4,000 Pioze ($1.50 × 2,500) 3,750 (9,500) Joint processing costs (12,900) Total gross margin $ 19,600

2. Gross margin percentage = Gross margin/Total revenue = $19,600/$42,000 = 0.4667, or 46.67% (rounded)

L-Ten Triol Pioze

Eventual market value $7,000 $ 20,000 $ 15,000 Less: Gross margin at 46.67% 3,267 9,334 7,001 Cost of goods sold $3,733 $ 10,666 $ 7,999 Less separable costs 1,750 4,000 3,750 Allocated joint cost $1,983 $ 6,666 $ 4,249

(Note: Allocated costs are rounded to the nearest dollar, so the allocated total is $12,898.) 3. An increase in the further processing cost of Triol will reduce the gross margin percentage and will decrease the joint cost allocated to Triol.

Total revenue $ 42,000 Further processing costs (13,500) Joint processing costs (12,900) Total gross margin $ 15,600

Gross margin percentage = $15,600/$42,000 = 0.3714, or 37.14% (rounded) L-Ten Triol Pioze Eventual market value $7,000 $ 20,000 $ 15,000 Less: Gross margin at 37.14% 2,600 7,428 5,571 Cost of goods sold $4,400 $ 12,572 $ 9,429 Less separable costs 1,750 8,000 3,750 Allocated joint cost $2,650 $ 4,572 $ 5,679

(Note: Allocated costs are rounded to the nearest dollar, so the allocated total is $12,901.)
