The cost of 85 shirts is 400+7.5*85=1037.5
The average per shirt is 1037.5/85=12.206
I would use the decimal form of 5.4%. It is very easy to convert a percentage into a decimal. All you have to do is move the decimal point two places to the left and remove the % sign.
5.4% = 0.054
So, 0.054 would be your multiplier.
<u>21.1</u>
Each number is 2.5 less than the previous one.
Well I know that 1/3 of 8 is 2.66666666667 I'm not sure the rest
Answer:
Theorem.
Step-by-step explanation:
Postulate/Axiom: Can't be proven or disproven.
Definition: Defines a term. Can be proven.
Theorem: Can be proven.
"Proof" (informal but it works): Triangle has 180°, that means two angles will be less than 180°. Right angles are 90°, that means two 90° angles add up to 180°. Something that is less than 180° is less than 180°.
This statement is provable, but doesn't necessarily define anything.
