Question 899256: You are planning to open a coffee shop and need to decide on how many COFFEE MACHINES to buy. The shop will be open for 8 hours in a day and you expect to sell on average 10,000 cups of coffee each day. One of the COFFEE MACHINES you are looking to buy can produce 20 cups of coffee in 10 minutes. You would like to have a 25% capacity cushion. How many of these coffee machines should you buy? (If rounding is needed,, round up to the nearest whole number)

8 hours a day ---> 1250 cups an hour

rate of 1 machine: 20 cups in 10 minutes --> 120 cups an hour

25% capacity cushion: 1250 * 5/4 = 1562.5 cups an hour

number of machines: 1562.5/120 = 13.02 ---> round up to 14
