Answer:
Step-by-step explanation:
We are supposed to write an inequality to determine the number of hot dogs per minute Joey must eat for the last 9 minutes to break his record.
Let d represent the number of hot dogs Joey eats per minute for the next 9 minutes.
We have been given that after 1 minute, Joey has eaten hot dogs.
Hot dogs eaten in next 9 minutes would be 9 times d that is .
Total hot dogs eaten by Joey would be hot dogs eaten in 1 minute plus next 9 minutes: .
Since to break the record Joey needs to eat more than 72 hot dogs. We can represent this information in an inequality as:
Therefore, our required inequality would be .
