Question

Each pot of coffee holds 6cups. we usually sell 10 cups every fifteen minutes. How many pots of coffee will you need to make during our two hours rush? How many pots of coffee you need to make?

Answer 1

14 pots
60 divided by 15 equals 4
for two hours you need 80 cups of coffee 
a pot can only make 6 cups 
6 times 14 equals 84 
After the two hour rush you will have 4 left over coffees

Answer 2

You will sell 14 pots and 4 will be the remainder.
