ok "mom"

150% means 150/100=1.5, so that 1.5 +1=2.5 X $60=$150.00 That is how much would the dress cost today.

1,800/2,200=81.82% This is the percentage target that you should aim for to loose weight. In other words, you are consuming 100-81.82=18.18% more food than you should.

1,650/86,000=.0192 X 100=1.92% The tax rate in your neighbourhood.

Please post your question VERY CLEARLY. Thanks.

680,000/3,907,000=17.40% of U.S. is used for food production.

no thats not what meant

Do you mean this=(3^4 - 24) / 3= If that is what you want, then we have:

(81 - 24) / 3=

57/3           =19

317/7100=4.46% of world population that lives in the U.S.

it depend on the type of skate

Express your answers rounded to the tenths place. 
(a) 301 is what percent of 140?  
(b) What is 205% of 54?

301/140=2.15 -1=115% greater than 140

54 X 3.05=164.7 which is 205% of 54.

Is it the absolute value?

Express your answers rounded to the tenths place. 
(a) 49.5 is what percent of 150? 
(b) 15 is 18% of what number

49.5/150=.33 or 33%

n.18=15

n=15/.18=83.3333...........etc.

Thank you both. I've had so much confusion trying to solve this one. I appreciate your help!

Add the individual numbers to get the total number of people:  203

Now, divide the number who chose orange by the total number:  27/203  =  0.113 (rounded)

Change into a decimal:  11.3%

To solve by addition or subtraction, you need to coefficients of either term to be the same (or negatives of each other).

If you multiply 0.3 by 11, you get 3.3, which will allow you to cancel out the c terms.

159 b + 3.3 c  =  1000   --->  leave this alone   --->   159 b + 3.3 c  =  1000

 2.3 b + 0.3 c  =  18      --->   times 11     --->          25.3 b + 3.3 c  =  198

Subtract down the columns:                                  133.7 b            =  802

Divide by 133.7:                                                                    b   =  5.9985  (approximately)

Substitute this value into either equation:  2.3 b + 0.3 ( 5.9985)  =  18      --->   b  =  14.011 (approximately)

(3/7)^5 * (9/7)^2 Then divide the answer by (3^4/7^3)^2 Simplify to exponential notation

=3/7, which is your exact answer=4.285714 X 10^-1

 $53143 X 1.33333=$70,857.16 The average family spending.

b = 5.9985 and c = 14.0115

Thank you so much!

According to www.whitehouse.gov, the government has about $2.1 trillion in receipts and $2.8 trillion in outlays (expenses) for 2013. 

What was the ratio of the government's expenses to it's receipts for 2013? 
Express this as a decimal rounded to the thousandths place. 

2.8/2.1=33 1/3% The government spent about 1/3 MORE than it took in.

This is just 2.8/2.1 ≈ 1.333

This illustrates Chris's solution:

.

24>-3r>-9    divde everrything by -3 and "reverse" the inequality signs

-8 < r < 3
