Question

Find the total cost.
purchase price = $434.95; tax rate = 4.5%

A. $454.52
B. $439.45
C. $435.40
D. $19.75

Answer 1

You can do it two ways.

Here's one of the ways.

Since the tax is 4.5%, you first need to find 4.5% of $434.95. That is the amount of the tax. Then you add the amount of the tax to the purchase price to find the total cost.

Answer 2

To find a percent of an amount, just multiply the percent by the amount.
Write the percent as a decimal and multiply it by the number.
To write a percent as a decimal, move the decimal point two places to the left.

Answer 3

Step 1. Find the amount of the tax.

4.5% of $434.95 = 4.5% * $434.95 = 0.045 * $434.95 = $19.57

Step 2. Add the amount of tax to the purchase price.

$434.95 + $19.57 = $454.52

Answer: the total cost is $454.52

Answer 7

Knowing that it's a multiple choice, I estimated.
10% of 435 is 43.5. This means that 4.5% is close to 20. So, the answer is going to be close to $455.
