Answer:

Explanation:
In this problem we know that a DVD costs $238 dollars.
Adrian bought 18 DVD's in total.
Meaning that since each DVD costs $238, we will have to multiply 18 by 238

==>

Now, here is the difference, the question asks approximately how much he will spend.
Meaning that we need to round to find our approximate.
4124
==> 4300
You could also say around 4000 to 5000 dollars
