This is the only question stopping me from getting 100% ive tried it on my own.

inflation took its toll, and the merchant had to mark the suit up 30 percent so it would sell for $156. what was the original price of the suit?

The original price was $120.00.

30 percent of $120.00 is $36 and if you add those together they equal $156.00.

I hope that makes sense and was helpful.

step-by-step explanation:

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.
