Answer: There are 3 DVD s that can be bought with under $100.
Step-by-step explanation:
Since we have given that
Cost of DVD = $15.99
Cost of Shipping = $ 9.99
Total cost per DVD would be
$15.99 + $9.99 = $ 25.98
Amount he has to spend no more than $ 100.
So, number of DVDs would be
100 ÷ 25.98 = 3.84
Hence, there are 3 DVD s that can be bought with under $100.
