Sonja bought a new van for her business. the cost of the van was $35,000, and she had to pay 6% sales tax. what was the total cost of the new van, including tax?

can someone explain how to get the answer

All we do is this:
We take the amount of money and multiply it by the tax applied:
$35000 × 0.06     (6%= = 0.06)
=2,100 is the value we get
We add this value to the original price:
$35,000+2,100= $37,100
$37,100

The correct answer is addition
