See a solution process below:

Because you can spend $39 or less, but not more, the inequality will have a "less than or equal to" operator.

So we can write the inequality as:

$$5x + $11y <= $39$

You have $39 to spend at the music store. Each cassette tape costs $5 and each CD costs $11. What is the linear inequality equation that represents this situation, let xx represents the number of tapes and yy the number of CDs?
