the hamburger without the tax?
$7.42
$6.70
$8.10
$6.94

Answer 1

$6.94

Explanation:

Let's say that the cost of the hamburger without tax in 100%. Then the price with tax is 108% because there is an 8% tax. Therefore, $7.50 corresponds to 108%. if we divide 7.50 by 108 we get 0.0694444 or 1%. Finally, we multiply by 100 to get 100% or the cost without tax which is $6.94.
