Allocated overhead per case $($to be computed$)$

Refer to Case $9-73.$ Jean Sharpe decides to gather additional data to identify the cause of overhead costs and figure out which

products are most profitable. She notices that $$30,000$ of the overhead originated from the equipment used. She decides to incorporate

machine$-$hours into the overhead allocation base to determine the effect on product profitability. Almond Dream requires two machine$-$

hours per case, Krispy Krackle requires seven hours per case, and Creamy Crunch requires six hours per case. Additionally, Jean notices

that the $$15,000$ per month spent to rent $10,000$ square feet of factory space accounts for almost $22$ percent of the overhead. The

assignment of square feet is $1,000$ to Almond Dream, $4,000$ to Krispy Krackle, and $5,000$ to Creamy Crunch. Jean decides to

incorporate this into the allocation base for the rental costs.

Because labor$-$hours are still an important cost driver for overhead, Jean decides that she should use labor$-$hours to allocate the

remaining $$24,500.$

CBI still plans to produce $1,000$ cases each of Almond Dream, Krispy Krackle, and Creamy Crunch. Assume that CBI can sell all

products it manufactures and that if it drops any products, it will use excess capacity to produce additional cases of the most profitable

product. Overhead will remain $$69,500$ per month under all alternatives.

Required

a$.$ Based on the additional data, determine the product cost and gross profit margin percentages of each product using the

three allocation bases $($labor$-$hours, machine$-$hours, and square feet$)$ to determine the allocation assigned to each product.

$b.$ Would management recommend dropping any product based on the criterion of dropping products with less than $10$

percent gross profit margin?

c$.$ Based on the recommendation you make in requirement $($b$),$ recalculate the allocations and profit margins to determine

whether any of the remaining products should be dropped from the product line. If so$,$ substantiate the profitability of

remaining products.
