when to use display or display-print
unless otherwise instructed, you will decide when to use the display only and when to use the print feature to work each set of problems. refer to the appendix, page 110, for a summary of display and printing features and applications.

expense comparison
managers analyze the operating expenses of their businesses each month. the present months expenses are compared with the previous months expenses to identify trends. if expenses are increasing by large percentages, the managers will want to determine the causes and avoid further increases.

percent of increase or decrease
it is often necessary to find the percent of change between two numbers as well as the amount of change. if the base (previous number) is smaller than the present number, there is a percent of increase. if the base is larger than the present number, there is a percent of decrease. use the following formula:

\\\frac{\text{amount of increase (or decrease)}}{\text{base}} = \text{percent of increase (or decrease)}\\

\\\frac{-4312}{865} = -43.12\\%\\

to work problems 46-55:

1. follow the steps for calculating amount and percent of increase or decrease.
2. when the present months amount is larger than the previous months amount, there will be a percent of increase. when the present months amount is smaller, there will be a percent of decrease.

Explanation:

Identify the given formula and data

We need to calculate the "Amount of Inc. or Dec." and the "Percent of Inc. or Dec." for each expense item (numbered 47 to 55) using the provided table data.

The formula for the amount of change is:

$$ \text{Amount of Change} = \text{Present Month} - \text{Previous Month} $$

The formula for the percent of change is:

$$ \text{Percent of Change} = \frac{\text{Amount of Change}}{\text{Previous Month}} \times 100\% $$

Calculate values for Bad Debts (47)

• Previous Month: \(432\)
• Present Month: \(220\)
• Amount of Change:

$$ 220 - 432 = -212 $$

• Percent of Change:

$$ \frac{-212}{432} \times 100\% \approx -49.07\% $$

Calculate values for Delivery Expenses (48)

• Previous Month: \(704\)
• Present Month: \(645\)
• Amount of Change:

$$ 645 - 704 = -59 $$

• Percent of Change:

$$ \frac{-59}{704} \times 100\% \approx -8.38\% $$

Calculate values for Depreciation (49)

• Previous Month: \(265\)
• Present Month: \(278\)
• Amount of Change:

$$ 278 - 265 = 13 $$

• Percent of Change:

$$ \frac{13}{265} \times 100\% \approx 4.91\% $$

Calculate values for Heat & Light (50)

• Previous Month: \(659\)
• Present Month: \(706\)
• Amount of Change:

$$ 706 - 659 = 47 $$

• Percent of Change:

$$ \frac{47}{659} \times 100\% \approx 7.13\% $$

Calculate values for Insurance (51)

• Previous Month: \(213\)
• Present Month: \(399\)
• Amount of Change:

$$ 399 - 213 = 186 $$

• Percent of Change:

$$ \frac{186}{213} \times 100\% \approx 87.32\% $$

Calculate values for Rent (52)

• Previous Month: \(878\)
• Present Month: \(809\)
• Amount of Change:

$$ 809 - 878 = -69 $$

• Percent of Change:

$$ \frac{-69}{878} \times 100\% \approx -7.86\% $$

Calculate values for Salaries (53)

• Previous Month: \(2,692\)
• Present Month: \(2,436\)
• Amount of Change:

$$ 2,436 - 2,692 = -256 $$

• Percent of Change:

$$ \frac{-256}{2692} \times 100\% \approx -9.51\% $$

Calculate values for Supplies (54)

• Previous Month: \(201\)
• Present Month: \(82\)
• Amount of Change:

$$ 82 - 201 = -119 $$

• Percent of Change:

$$ \frac{-119}{201} \times 100\% \approx -59.20\% $$

Calculate values for Taxes (55)

• Previous Month: \(445\)
• Present Month: \(596\)
• Amount of Change:

$$ 596 - 445 = 151 $$

• Percent of Change:

$$ \frac{151}{445} \times 100\% \approx 33.93\% $$

Answer:

No.	Amount of Inc. or Dec.	Percent of Inc. or Dec.
47	\(-212\)	\(-49.07\%\)
48	\(-59\)	\(-8.38\%\)
49	\(13\)	\(4.91\%\)
50	\(47\)	\(7.13\%\)
51	\(186\)	\(87.32\%\)
52	\(-69\)	\(-7.86\%\)
53	\(-256\)	\(-9.51\%\)
54	\(-119\)	\(-59.20\%\)
55	\(151\)	\(33.93\%\)
