Answer:
15.8 dollars per dvd.
Step-by-step explanation:
<em>Our equation for this problem is:</em>
<em />
<em>v = how much one dvd costs</em>
<em />
<em>2v + 3.15 - 1 = 33.75</em>
<em>2v +3.15 =34.75 (added 1 on both sides)</em>
<em>2v = 31.6 (subtracted 3.15 from both sides)</em>
<em>v = 15.6 (divided by 2 on both sides) </em>
<em />
They should be both divisible and no decimals
