Finding the Correct Inequality for Maria's Concert Tickets

Maria is planning to buy tickets for a concert. The price of each ticket is $12. She also has to pay a one-time reservation fee of $20. If Maria's budget for tickets is $80, which of the following equations best represents the situation?

Let x be the number of tickets Maria can buy. The total cost of the tickets is given by the equation:

$$12x + 20 ext{ (reservation fee)} ext{ must be } \leq 80 ext{ (budget)}$$
