Answer 1

$34.67

Explanation:

Samuel orders four DVDs from an online music store. Each DVD costs $9.99.

Therefore, the cost of four DVD is $(9.99 × 4) = $39.96

Now, he has a 20% discount code, and sales tax is 6.75%.

Therefore, the final cost of the 4 DVD will be
`39.96(1 - (20)/(100) + (6.75)/(100)) = 39.96 * 0.8675 = 34.67` dollars (Approximate)

Therefore, the total cost of the order is $34.67 (Answer)
