Two stores sell the same computer for the same original price. store a advertises that the computer is on sale for 25% off the original price. store b advertises that it is reducing the computer’s price by $180. when brittany compares the sale prices of the computer in both stores, she concludes that the sale prices are equal.

let p represent the computer’s original price.

what equation models this situation?

a. 0.75p=p+1800.75p=p+180

b. 0.25(p−180)=p0.25(p−180)=p

c. 0.25p=p−1800.25p=p−180

d. 0.75p=p−180

 Option 'D' is correct.

Step-by-step explanation:

Let the original price of computer be p.

Store A advertises that he compute is on sale for 25% off the original price.

Amount of discount would be

So, Price after discount becomes

Store B advertises that it is reducing the computer's price by $180.

So, Price after reduction becomes,

According to question, she concludes that the sale prices are equal,

So, our equation becomes,

Hence, Option 'D' is correct.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

answer:

a=9
