Romashka-Z-Leto [24]

Answer:

$107.38

Step-by-step explanation:

FIRST WAY:

Since you have a 20% discount, that is equivalent to two-tenths of $134.22

Step 1: find the discount.

0.2 x 134.22 = 26.844 (round to 26.84)

Now that you have the discount, simply subtract that discount from your original price.

Step 2: find the final price.

$134.22 - $26.84 = $107.38

SECOND WAY:

A faster way to solve problems like this is to find the percentage of cash you are going to pay with the coupon. To do so, simply convert your percentage value to its corresponding decimal value relative to the original.

Layman's terms: just subtract the 20% from 100% to get 80%.

Step 1: find the percentage to be paid.

100% - 20% = 80% OR 1 - 0.2 = 0.8

Now that you have the percentage you need to pay, just multiply that percentage by the original amount.

Step 2: find the final payment.

$134.22 x 0.8 = $107.38

Why is the product of negative reciprocals always -1?

erik [133]

Answer:

please check the explanation.

Step-by-step explanation:

Let suppose we have a number = n

n≠0

The negative reciprocal of 'n' = -1/n

Taking the product of 'n' and its negative reciprocal '-1/n':

$n\left(-\frac{1}{n}\right)$

remove parentheses: (-a) = -a

$=-n\frac{1}{n}$

$\mathrm{Multiply\:fractions}:\quad \:a\times \frac{b}{c}=\frac{a\:\times \:b}{c}$

$=-\frac{1\times \:n}{n}$

$\mathrm{Cancel\:the\:common\:factor:}\:n$

$=-1$

Canceling the common factor (the number itself) will bring -1.

It proves that the multiplication of any number and its negative reciprocal will always yield -1.
