Answer 13

(57,000/50,000 )X100 that is the increase from the starting value , minus from 100% you will get the percentage increase

11,500 - 7,130 = ?
? / 11,500 = %

A company is expanding its building area from 15,500 square feet to 21,390 square feet. What is the percentage increase of the area of the building space?

You'd do (15,500/21,390)X100 right?

Answer 18

(The Second Value / The First Value ) X100 gives the total increase or decrease , if its increase then minus -100% , if its decrease then 100%-value.

Answer 21

The value of a professional basketball player's autograph rose 30% in the last year. It is now worth $325.00. What was it worth a year ago?

What about this one?

Answer 22

Then 325.00 is the new value , Divide By 130% you will get the 1% then multiply By 100 you will get the 100% which is the old autograph.

Answer 23

269$ i think

Answer 24

$250

325 / .130 = 2500 X 100 = 250000

If you put the decimal it'd be $250.00 :D

Answer 25

Can you help me with this question as well?

A pair of shoes usually sells for $55. If the shoes are 20% off, and sales tax is 8%, what is the total price of the shoes, including tax?

Insert Logic As Well :)

Answer 26

Ya , I meant 249.5 , My calc is a bit sensitive.

Answer 27

Sale tax is abduct able from the ending sale price right?

Answer 28

so you decrease the 55 by 20% then abduct the taxes which is the 8% from the new price by the same method

Answer 29

Ohk

Answer 30

(55/100) x20=11 , then the new price is 55-11=44 , then abduct the taxes which is 8% from the ending price (44/100)x8=3.52 , then the final value for the price will be 44-3.52=40.48.

Answer 31

If the tax is abucted from the initial price then the value will be 39.6 as it will be dec by 28%

Answer 32

That answer isn't correct..
The answer choices for this question is:
A $48.40
B $50.49
C $44.55
D $47.52

Answer 33

its 40.48 , not 48.40 check again.

Answer 34

w8 , You mean then total price including the tax , so tax is added to the price?

Answer 35

Yep

Answer 36

it will be 47.52$

Answer 37

i thought taxes are abducted not added ,sry.

Answer 38

Oh..

Answer 39

so instead decreasing the tax value you add it to the final price , which is the 8% from the ending price which is 44.

Answer 40

Okay

Answer 41

(44/100 )x8 +44=47.52
