Answer:
We know the amount of discount is $10. Therefore, mentally we know the
following:
Sale price = $100 - $10 = $90
We know the Sales Tax is 5%. We can first take 10% of 90 because all we have to
do is move the decimal point one place to the left. Therefore, 10% of 90 equals
$9. Then we divide this number in half to represent 5%. Therefore, 9/2 = $4.50.
The Sales Tax is $4.50.
Total Cost = $90 + $4.50 = $94.50 Explanations may vary.
Sale Price = $90
Sales Tax = $4.50
Total Cost = $94.50
