Question

Joey Chestnut is trying to break his own record for eating the most whole hot dogs in
\[10\] minutes. He needs to eat more than
\[72\] hot dogs to break his record. After
\[1\] minute, Joey has eaten

\[11 \dfrac{1}{4}\] hot dogs. Let
\[d\] represent the number of hot dogs Joey eats per minute for the next
\[9\] minutes.
Which inequality represents the number of hot dogs per minute Joey could eat for the last
\[9\] minutes to break his record?
Choose 1 answer:
A

\[11\dfrac{1}{4}+9d>72\]
B

\[11\dfrac{1}{4}+9d=72\]
C

\[11\dfrac{1}{4}d+9>72\]
D

\[11\dfrac{1}{4}d+9=72\]

Answer 1

Total eaten = 11 1/4 (first minute) + 9d (next 9 minutes). To break the record he needs more than 72, so

11 1/4 + 9d > 72.

Answer: A
