a CD usally sells for 14.00 if the CD is 30% off and sales tax7% whats the total price of the price of the CD including tax
Ostrovityanka [42]
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
