First you will get the sale price.
you need to convert the percentage to a decimal and to do that you move the decimal over twice:
30% = .30
then multiply the CD price by the decimal
$14.00 X .30 = $4.20
then you have the sales price but you need to find the tax price
to do that you move the decimal of the tax percentage over twice
7% = .07%
then multiply by the price after the sale included
.07 X $4.20 = $0.29
you have how much the tax would be
to get the total price you add the tax to the sales price
$0.29 + $4.20 = $4.42
the price you would be paying for this CD including tax is $4.42
It should be 15% I think I’m right
Step-by-step explanation:
it's like the y in an equation
Here,
Volume of cylinder = 539^3 cm
Circumference = 22 cm
Height = ?
Now,
Circumference = 2πr
or, 22 = 2*22/7*r
or, 22 = 44/7*r
or, 154/44 = r
◆ r = 3.5 cm
Then,
Volume of cylinder = πr^2h
or, 539 = 22/7*(3.5)^2*h
or, 539 = 22/7*12.25*h
or, 539 = 269.5/7*h
or, 3773 = 269.5*h
or, 3773/269.5 = h
◆ h = 14 cm
I hope it's help you...
I hope you understand...

Answer:
There is two equations because it has to have two. One is going to have a positive answer and the negative answer. It just depends on the question and what it is asking g you
