First we need to find what is 20% off $23,999
1) = 20/100 x 23,999= $4,799
To find the decrease over 6 years :
2)= $4,799 x 6 = $28,798.8

Finally
= 28,798.8-23,999= $4,799.8

$4,799.8 is the final value.

Which is the correct answer ?????

Damm [24]

<h3>Answer: True</h3>

Explanation:

Technically you could isolate any variable you wanted, from either equation. However, convention is to pick the variable in which isolating it is easiest, and most efficient.

The key thing to look for is if there's a coefficient of 1. This is found in the second equation for the y term. Think of -4x+y = -13 as -4x+1y = -13. Due to the coefficient of 1, when solving for y we won't involve messy fractions.

If you were to solve for y, then you'd get y = 4x-13, which is then plugged in (aka substituted) into the first equation. That allows you to solve for x. Once you know x, you can determine y.

A CD usually sells for $15.00. If the CD is 10% off, and sales tax is 5%, what is the total price of the CD, including tax?

dybincka [34]

Answer:

<em>The total price of the CD is $14.18</em>

Step-by-step explanation:

<u>Percentages </u>

We can compute additive or subtractive percentages by using these formulas. If we have a number X and want to increase it by Y%, then the increase is xY/100. Thus the new value for the number is x+xY/100 or equivalently

$X(1+Y/100)$

If we want to decrease by Z%, the new value is

$X(1-Z/100)$

The regular price for a CD is X=$15. The CD is Z=10% off, so the sale price is

$15(1-10/100)=\$13.5$

But we have to add the tax of Y=5%, so the final value is

$13.5(1+5/100)=\$14.18$

The total price of the CD is $14.18
