Answer:
5x + 10y ≤ 47
Explanation:
Here, x represent the number of tapes and y the number of CDs.
Since, Each cassette tape costs $5 and each CD costs $10.
Thus, the total cost x taps and y CD's = 5x + 10y
Also, we have $ 47 to spend,
Thus, Total cost can not be exceed to $ 47,
⇒ 5x + 10y ≤ 47
Which is the required inequality that represents this situation.
