Respuesta :
The headphones were discounted by 30%, so this means he paid 70% of the original price ( 100% - 30% = 70%)
Multiply the original price by 70% to find the discounted price:
70% = 0.70
39.99 x 0.70 = $27.99
Part A) Multiply the discounted price by the sales tax 6%:
6% = 0.06
27.99 x 0.06 = 1.679 = $1.68 total sales tax.
Part B) Add the discounted price and the sales tax to get the total cost:
27.99 + 1.68 = $29.67 total cost.
Part A
Amount he paid after discount = 39.99 - 0.3* 39.99
= $27.99 before tax
Tax on this discounted price = 27.99 * 0.06 = $1.68 answer
Part B
Total amount paid = 27.99 + 1.68 = $29.67 Answer
