Answer:
The restaurant would sell more than a hundred omelets. 104.4 omelets
Explanation:
The restaurant serves breakfast from 6:09 am until 10:30am. This means 4 hours 21 minutes. One hour is 60 minutes. Four hours will be 240 minutes. Then, 4 hours 21 minutes will be 261 minutes.
If 6 omelets are sold each 15', how many omelets will be sold in 261 minutes. This rule of three render that 104.4 omelets will be sold in 261 minutes
