You earn $100 plus 1/5 of your sales each week. what dollar amount of sales do you need this week to earn $600?

You'll need $2,500 in sales this week to end up with $600 in income for the week.

Step-by-step explanation:

Let s represent the dollar amount of the total sales for the week.

The commission earned on such sales is 1/5, or 0.20, of s:

Commission:  0.20s

Then the correct expression for your weekly income is:

$100 + 0.20s = $600.

Solving for s, subtract $100 from both sides.  Then 0.20s = $500, and through division we get  s = $2,500.

You'll need $2,500 in sales this week to end up with $600 in income for the week.

answer: 15

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.
