Question

What is the value of z?

Answer 1

Explanation:

Item 1:

Discount = Original price - discount price

= 22.50 - 13.50

= $ 9

Discount percentage =
`(9)/(22.50)*100\\\\`

= 40%

Discount percentage = 40%

Tax = 14.31 - 13.50 = $0.81

Tax% =
`(0.81)/(13.50)*100\\\\` = 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
