Final answer:
To find the correct inequality to complete the sentence, subtract the cost of entering the fair and the cost of riding the rides from the total money Amari has. Set up the inequality so that the result is less than or equal to 0.
Step-by-step explanation:
To find the correct inequality to complete the sentence, we need to express the amount of money Amari has left after she enters the fair. Let's start by writing an equation to represent the total amount of money Amari has:
Total money = $40
Next, we subtract the cost of entering the fair ($12) and the cost of riding the rides (3t), where t represents the number of tickets Amari buys:
Total money - $12 - $3t
Since we want to find the inequality that represents the amount of money Amari has left, we can set up the inequality:
Total money - $12 - $3t ≤ 0
This inequality states that the total money minus the cost of entering the fair and the cost of riding the rides should be less than or equal to 0, indicating that Amari has no money left.
