You have $39 to spend at the music store. Each cassette tape costs $5 and each CD costs $11. Write a linear inequality that represents this situation. Let x represent the number of tapes and y the number of CDs.

5x + 11y ≥ 39

11x + 5y ≤ 39

5x + 11y ≤ 39

11x + 5y ≥ 39

1 answer

In this situation, you need to write a linear inequality to represent the total cost constraint. You have $39 to spend at the music store. Each cassette tape costs $5, and each CD costs $11. Let \( x \) represent the number of tapes and \( y \) represent the number of CDs.

The total cost for \( x \) tapes and \( y \) CDs can be expressed as \( 5x + 11y \). Since you have $39 to spend, the inequality representing this situation is:

\[ 5x + 11y \leq 39 \]

So the correct answer is:

\[ 5x + 11y \leq 39 \]
