Answer:
Step-by-step explanation:
<u>Item 1:</u>
Discount = Original price - discount price
= 22.50 - 13.50
= $ 9
Discount percentage =
= 40%
Discount percentage = 40%
Tax = 14.31 - 13.50 = $0.81
Tax% = = 6%
Tax percentage = 6%
<u>Item 2:</u>
Tax = 6% of 16.20
= 0.06 * 16.20
= 0.972
Tax = $ 0.97
Total price (including tax )= 16.20 + 0.97 = $ 17.17
x = $ 17.17
<u>Item 3:</u>
Discount = 40% of 32.50
= 0.4 * 32.50
= $ 13
y = 32.50 -13
y = $ 19. 50
Tax = 6% of 19.50
= 0.06 * 19.50
= 1.17
z = 1.17 + 19.50
Z =$ 20.67
