Final answer:

On Black Friday, Kat paid a 6.5% tax on her purchase of airpods.

Step-by-step explanation:

To find the percent tax Kat paid, we need to divide the tax amount by the total cost of the purchase and then multiply by 100.

First, subtract the tax amount from the total cost to find the cost of the item without tax. $137.39 - $8.39 = $129.

Next, divide the tax amount by the cost without tax and multiply by 100 to find the percent tax: $8.39 / $129 * 100 = 6.5%.

ANSWER

She paid 6.5% tax

EXPLANATION

If Kat paid $137.39 including $8.39 tax, then the 100% of the value of the airpods is:


137.39-8.39=129

$129 is the total for the airpods. This is the 100%. We want to know what percentage of 120 is 8.39:


8.39*(100)/(129)=8.39*0.7752=6.5

The tax was 6.5%
