lary plans to buy 5 tickets to go to an orchestra concert with her friends. She expects to pend at least $90 on the tickets.

et x represent how much Mary expects each ticket to cost. Which inequality describes the problem?

The inequality that describes the problem is: 5x ≥ 90.

The inequality that describes the problem is:

5x ≥ 90.

This inequality represents that Mary plans to buy 5 tickets (5x) and she expects to spend at least $90 on the tickets (≥ 90).

To represent the problem mathematically, we can use an inequality. Since Mary expects to spend at least $90 on the tickets, we can write the inequality as:

5x >= 90

This inequality states that the product of 5 (the number of tickets) and x (the cost per ticket) should be greater than or equal to $90.
