Answer:
The sales tax rate is 8%.
C. The sale price is 20% less than the regular price
Step-by-step explanation:
Here are the options to this question :
A) The sales tax rate is 6%
B) The sales tax rate is 8%.
C. The sale price is 20% less than the regular price
Sales tax rate = (tax paid / discounted selling price) x 100
tax paid = amount customer paid - discounted selling price
$73.44 - $68 = $5.44
($5.44 / $68) x 100 = 8%
The sales tax is 8%
Sales price = (discount / initial price) x 100
discount = $85 - $68 = $17
($17 / 85) x 100 = 20%
