Answer:
the answer is C
Step-by-step explanation:
magazine = $4.99
book = $12.99
DVD = $17.99
total bill
= magazine + book + DVD
= $4.99 + $12.99 + 17.99
= $35.97
tax 6%
amount of tax
= 6% × total price
= 6/100 × $35.97
= $2.16
total bill including 6% tax
= total bill + amount of tax
= $35.97 + $2.16
= $38.13
