Samuel orders four DVDs from an online music store. Each DVD costs $9.34. He has a 25% discount code, and sales tax is 7%. Round sales tax amounts to the nearest cent. What is the total cost of his order?

Answer: $31.02

Step-by-step explanation:

Cost of four DVDs at the rate of $9.34 per one = $9.34 x 4

= $37.36

Discount code = 25% of the cost price

= 25% of $37.36

= $9.34

Therefore Cost Price of the 4 DVD = $37.36 - $9.34

= $28.02

Sale tax percentage = 7% of the cost price

= 7% of $37.36

=$2.61

To the nearest cent = $3

Therefore, the total cost of his order = $28.02 + $3

= $31.02.
