Gekata [30.6K]

Answer:

$46.746

Step-by-step explanation:

Allen is buying a video that originally cost = $ 49

Discount coupon = 10%

Sales tax= 6%

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{100-10}{100}×\frac{100+6}{100}

Hence, the price of video after discount coupon and sales tax= $ 49 ×\frac{90}{100}×\frac{106}{100}

Price of video after discount coupon and sales tax= $ 49 × 0.9× 1.06

price of video after discount coupon and sales tax=  $46.746

Hence, the correct answer is $46.746
