Ok i have calculated this and i srill havent got the right answer

66 x 0.3 = 19.8
66-19.8 = 46.2
66 x 0.05 = 3.3
46.2 + 3.3 = 49.5

B

1. The original price of the shoes is 100% of the price of the shoes.
If you discount them by 30%, you will only pay 100% - 30% = 70% of their original price.

70% of $66 =

= 70% * $66

= 0.7 * $66

= $46.2

2. Now you have an item that costs $46.20, and you need to pay 5% tax on it.

$46.20 is 100% of the price of the shoes.
If you add 5% to the price, you need to pay 100% + 5% = 105% of the price.

105% of $46.20 =

= 105% * $46.20

= 1.05 * $46.20

= $48.51

$48.51
