PROBLEM 1
A. CVP analysis may be used to perform "what if" analyses that allow management
to study the effects of various operating changes on firm profitability. For
example, the effects of changes in selling price, variable costs, fixed costs, and
volume may be explored by manipulating the CVP model with different values for
these items.
B. Three additional assumptions for the CVP model are:
The per-unit selling price is constant.
Cost behavior is linear over the relevant rangethat is, variable cost per unit
is constant and fixed costs in total are constant.
The number of units manufactured and sold is the same.
C. The shift toward more apartments and fewer single-family homes and upscale
condominiums may mean that demand for the Economy models will increase
relative to the demand for Prestige models. The rental apartment generally will
be used for households with lower income.
The shift in buying habits could create a problem since the CVP model assumes a
constant sales mix. The mix change could invalidate previous CVP studies.
PROBLEM 2
A negative contribution arises because selling price is less than variable cost.
Several reasons may create this situation: (1) inefficient operations and, thus, higher
costs; (2) a very competitive marketplace, which has forced the firm to lower its
price; and (3) a loss leader whereby Maddox is purposely taking a loss on product
no. H647 with the intent of stimulating customer demand for other, more profitable
products.
Each unit sold will lower overall profitability so, technically, Maddox should not
continue to sell product no. H647. However, for reasons (2) and (3) above, the firm
might decide otherwise and stick with this "loser."
PROBLEM 3
A. Mathematically, operating leverage is contribution margin divided by net income.
The degree of operating leverage indicates a company's ability to operate with a
given amount of fixed cost relative to variable cost.
B. The increase in selling price with no change in units sold will increase both
contribution margin and net income by the same peso amount. The percentage
change in net income will be greater than the percentage change in contribution
margin and, thus, the operating leverage factor will decrease.
C. The decrease in variable costs will increase the contribution margin, but net
income will not change because total costs remain the same. The operating
leverage factor will therefore increase.
PROBLEM 4
A. Variable manufacturing costs typically decrease in a flexible manufacturing
environment and total fixed costs increase. Automation (along with
accompanying depreciation, lease, and maintenance costs) and fewer people
normally account for this change. The break-even point, as a result, often
increases.
B. When a company first changes to JIT, there is likely to be a drop-off in
inventories. However, the assumption of no significant change in inventories will
probably not be violated for an ongoing JIT user. Any accompanying level
changes are not likely to be significant relative to the volume of production and
sales.

D.
The contribution margin is the amount that each unit (pizza) contributes
toward covering fixed cost and producing a profit. Once a company's fixed
costs are covered, operating income will increase by the amount of the
contribution margin. Mathematically, it is computed as the difference between
selling price and the variable cost per unit.

The contribution statement would be used because the fixed and variable
costs must be separated in order to measure the effect of a volume change
on total costs. Unfortunately, a traditional income statement does not
provide the necessary information.

PROBLEM 12
A. Given that both locations have identical sales, Austin has a higher level of
variable cost (P1,600,000 vs. P300,000) as indicated by a smaller contribution
margin. Madison, in contrast, has a higher amount of fixed cost (P1,550,000 vs.
P250,000) because of the larger contribution margin and a net income equal to
that of Austin.
B. Operations with sizable labor forces have high variable costs; conversely,
automated facilities give rise to high fixed costs (e.g., depreciation, lease
payments, maintenance). Thus, Barry's philosophy is most closely associated
with the Austin facility, and Larry's seems consistent with the cost structure in
Madison.
C. Madison: P1,700,000 P150,000 = 11.33
Austin: P400,000 P150,000 = 2.67
D. Madison would experience a larger percentage change in net income because it is
more highly leveraged than Austin. Mathematically, the percentage change in
income can be computed by multiplying the operating leverage factor by the
percentage change in sales revenue.
