Which of the following expressions is correct?

masya89 [10]

Answer:

The correct answer is: [A]: " -(-21) = 21 " .

________________________________

Step-by-step explanation:

________________________________

Let us examine the answer choices given.

________________________________

Choice: [A]: " -(-21) = 21 . This is correct;

→ since a "negative value of negative value" is a "positive value" ; as shown in this case. The equal sign holds true, since the

"negative of a "negative value" is equal to the "positive value" of that same "positive value equivalent."

________________________________

Choice: [B]: " -(-21) = -21 . This is incorrect. As explained above:

→ a "negative of negative" is a "positive value" .

This answer choice shows that a "negative of negative"; is a "negative" :

→ which is: INCORRECT.

→ Rule out: "Choice: [B]."

________________________________

Choice: [C]: " -(21) = 21 . This is incorrect. The "negative" value [of a positive integer is not equal to the "equivalent positive value" of that same integer.

→ Rule out: "Choice: [C]."

________________________________

Choice: [D]: " (-21) = 21 "; This is incorrect. In a conceptually similar way as explained above—(for "Answer Choice: [C]" — the "negative value equivalent" of an integer is NOT equal to the "equivalent positive value" [of that same integer.].

→ Rule out: "Choice: [D]."

________________________________

The correct answer is: [A]: " -(-21) = 21 " .

PART A

Given:

f(x) = 0.69(1.03)x

To find:

If the price of the product is increasing or decreasing and by what percentage

Steps:

we know the formula to find the price of Product A per year, so

f(1) = 0.69 * 1.03 * 1

Price = $0.7107

f(2) = 0.69 * 1.03 * 2

Price = $1.4214

Here the Price of Product after 2 years is greater than the price of Product after one year. So the price of the product A is increasing.

Now to find percentage increase,

Percentage increase = $\frac{FV-SV}{SV}*100$ (FV = final value, SV = starting value)

Percentage increase = $\frac{1.4214 - 0.7107}{0.7107}*100$

Percentage increase = $\frac{0.7107}{0.7107}*100$

Percentage increase = 100 %

Therefore, the percentage increase of Product A is 100%

PART B

Given:

Price of product B in 1st year = $10,100

Price of product B in 2nd year = $10,201

Price of product B in 3rd year = $10,303.01

Price of product B in 4th year = $10,406.04

To find:

Which product recorded a greater percentage change over the previous year

Steps:

We need to find the percentage change of Product B and Product A of each year. We know that the percentage change of product A is 100 % for each year, so we only need to calculate for product B

PC of product B from 1st to 2nd year = $\frac{10,201-10,100}{10,100}*100$
