Answer:
Step-by-step explanation:
Item 1:
Discount = Original price - discount price
= 22.50 - 13.50
= $ 9
Discount percentage = [tex]\frac{9}{22.50}*100\\\\[/tex]
= 40%
Discount percentage = 40%
Tax = 14.31 - 13.50 = $0.81
Tax% = [tex]\frac{0.81}{13.50}*100\\\\[/tex] = 6%
Tax percentage = 6%
Item 2:
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
Item 3:
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
