Answer:
$55.12
Step-by-step explanation:
First, we will take 20% off of the shoes.
65/100= .65 This is 1%
Multiplied by 20 to equal $13
We will then take the 20% off of the initial price
$65-$13= $52
Next, we need to add the sales tax
52/100= .52 This is 1%
Multiplied by 6 to equal 3.12
We will then add the sales tax to the new price
$52 + $3.12 = $55.12 total
350 is 100x3.5 so 350 is 3.5 as a decimal and 350%
