A CD usually sells for $13.00. If the CD is 20% off, and sales tax is 6%, what is the total price of the CD, including tax?A.$10.34
B.$11.02
C.$11.13
D.$11.18

Answers

Answer 1
Answer: If it is 20% off, we multiply the decimal form of 20%(0.2) to 13. 0.2 x 13 equals 2.6, and we subtract 13 by this to get 10.4. 10.4 is the price of the CD after the 20% off, so now we need to figure out the price after tax. Since tax is 6%, we can multiply the decimal form of it(0.06) to the discounted price. 10.4 x 0.06 equals 0.624, and 10.4 + 0.624 equals 11.024. So the total price of the CD including the discount and tax is $11.024.

Answer 2
Answer: First, find 20% of 13:

\sf0.20*13=2.6

Subtract this from the price:

\sf13-2.6=10.4

Now find 6% of this:

\sf0.06*10.4=0.624

Now add this to the discounted price:

\sf10.4+0.624=11.024

So the price is approximately $11.02

The value of an antique mirror increased by 40% since juliet bought it. Its value is now $350. What amount did juliet originally pay for the mirror.

Answers

the problem states that the current value is $350 and that is the original price plus 40%, that is $350 is the 140%, the question is how much is the 100%, or the original price, lets use a rule of three, simple, direct proportion:
140% --------> $350
100% --------> x
x = (100)(350)/140
x = 250
that is the original price, $250
350(0.4) 140 and that how i get the answer.

Ok, so to do this you need to set up a proportion. They give you miles per gallon. So your proportion looks like this: m/g=m/g. Now subsitute in what they give you. The proportion looks like this: 349.2. X -------- = ---- 38.8 14.6 Your answer should be 131.4 miles Hope this helps!

If A and B are in a ration a:b then for each a of A there are b of B.

Hence for each 4 soccer players there is 1 volleyball player.
The number of soccer players is 4 times the number of volleyball players (the top left answer is correct).
If there are 4 volleyball players, there are thus 4*4=16 soccer players (and not 12)

If there are 16 soccer players, there are then 16/4=4 volleyball players, thus a total of 20 players: the third answer (bottom left) is wrong

If there is 1000$ in the lockbox what year will it be worth 64,000$ at 24% interest?

Answers

Hey there!

First, set up an exponential equation that represents the rate at which your original amount, 1000, gains interest:

y = 1000(1.24)^x

Y represents the value after X years. 1.24 represents the rate at which the money gains interest, 1 + 0.24 (your 24% interest rate in decimal form). 1000 is your original amount.

Now, set this equation equal to 64000, graph y = 64000 and y = 1000(1.24)^x on a graphing calculator, and see where the two equations intersect in order to solve for x.

They intersect when x is about 19.334, as seen in the graph below (it is very zoomed in so that you can see where the two functions intersect). Therefore, it will be about 19 years after the year in which you deposited the 1000 dollars before the money is worth 64000 dollars.
