Answer:
The restaurant expect to sell more than 100 omelets
Explanation:
we know that
The restaurant sell 6 omelets every 15 minutes
The restaurant serves breakfast from 6:00 am until 10:30 am
10:30 am-6:00 am=4.5 hours
Convert 4.5 hours to minutes

so
using proportion
Find out the number of omelets that the restaurant expect to sell in 270 minutes
Let
x ----> the number of omelets


therefore
The restaurant expect to sell more than 100 omelets
