The tax rate as a percent, r, charged on an item can be determined using the formula 100( – 1) = r, where c is the final cost of the item and p is the price of the item before tax. Louise rewrites the equation to solve for the final cost of the item: c = p(1 + ). What is the final cost of a $40 item after an 8% tax is applied?

Answers

Answer 1

Answer: The question is asking us to calculate the final cost of the item after the tax is applied. The price of item before the tax is: P = $40 and the tax rate as a percent is 8%. It means that r = 0.08. And the formula is: C = P * ( 1 + r ). Finally: C = $40 * ( 1 + 0.08 ) = $40 * 1.08 = $43.20. Answer: The final cost is $43.20.

Why might you want to use thecommutative property to change the order of the integers in the following sum before adding?

Answers

Answer :

You can use commutative property or can not be .It is not necessary to use it for given addition of integers.

Step-by-step explanation:

We are given that an expression

$-80+(-173)+(-20)$

By simplfy simply without using commutative property

$-80-173-20=-273$

Because minus minus is plus then all integers will be added.

Simplfy by using commutative property

$-80+(-173)+(-20)$

$-80+(-20)+(-173)$ (Commutative property a+b=b+a)

$-100+(-173)=-273$

The answer should not change .Hence, if you want use commutative property to change the order of the integers then answer does not effected.So, you can use it or can not be .

u would do this because no matter the order, the answer will be the same

A jar contains 45 red candies and 60 black candies suppose a candy is selected at random what are the odds agianst selecting red candy

Answers

first you add up the red and black so see how many she has total.
45 + 60= 105
then if you need to find the probability of the red candies you put
45/ 105
then you can simplify it so it would be 8/21

45+60=105
45/105= 8/21
