Answer:
d > 6 3/4
Step-by-step explanation:
Given that:
72 hot dogs in 10 minutes is required to break Record ;
Consumption after 1 minute = 11 1/4 hot dogs
Number of hotdogs consumed per minute for the next 9 minutes = d
Number of consumption per minute required to break record :
d = (72 - 11 1/4) / 9
d = (60 3/4) ÷ 9
d = (243 / 4) * 1/9
d = 243 / 36
d = 6 3/4 hotdogs per minute
Hence, to break record. Consumption must be > 72 hotdogs in 10 minutes
Hence,
d > 6 3/4
