Question

russell bought a CD player that costs $120 before it went on sale for 15% discount. If he paid 5% sales tax on the sale price, how much did russell pay for the cd player?

Answer 1

$107.10

Explanation:

The original price of the CD player is $120 and we need to take 15% off.

We can find how much we need to subtract by multiplying 120 by .15, which equals 18. Then we can subtract that from 120, to get a sales price of $102.

A shortcut is subtracting 15 from 100 to get 85, and then doing 120*.85 = 102.

From the sales price of 102, there's a 5% tax to add on. 102 * .05 = 5.1

102+5.1 = 107.1

Answer 2

$107.10

Explanation:

First, find the discount.

Multiply the discount rate, 15% by the price of the CD player, $120

discount rate * price

15% * $120

Convert 15% to a decimal. Divide 15 by 100 or move the decimal place two spots to the left.

15/100= 0.15 or 15.0 --> 1.5 --> 0.15

0.15 * $120

$18

Since it is a discount, subtract $18 from the regular price of $120.

$120-$18

$102

Next, find the tax.

Multiply the tax rate, 5% by the price of the discounted CD player, $102

tax rate * discounted price

5% * $102

Convert 5% to a decimal. Divide 5by 100 or move the decimal place two spots to the left.

5/100= 0.05 or 5.0 --> 0.5 --> 0.05

0.05* $102

$5.10

Since it is tax, add $5.10 to the discounted price of $102.

$102 + $5.10

$107.10

Russell will pay $107.10 for the CD Player after a discount and tax.
