On Monday, a jacket cost $36.95 and a shirt cost $21.42. On Friday, the jacket was discounted by 20%, and the shirt was discounted by 1/3. What is the total price of the jacket and shirt on Friday, before sales tax?

Step-by-step explanation:

On Monday, a jacket cost $36.95 and a shirt cost $21.42. On Friday, the jacket was discounted by 20%. It means that the amount that was taken off the jacket is

20/100 × 36.95 = 0.20 × 36.95 = $7.39

The cost of the jacket on Friday would be

36.95 - 7.39 = $29.56

Also, on Friday, the shirt was discounted by 1/3. It means that the amount that was taken off the jacket is

21.42/3 = $7.14

The cost of the shirt on Friday would be

21.42 - 7.14 = $14.28

The total price of the jacket and shirt on Friday, before sales tax is

29.56 + 14.28 = $43.84

answer:  

123455421

step-by-step explanation: easy

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.
