Recent studies show that 52 out of 100 adults consume one cup of coffee daily. If a university employs 3,750 people.

A. How many of these employees will not drink coffee for one day?

B.If the coffee machine charges $ 0.95 per cup sold, how much money will the coffee machine generate in a work week (5 days)?

Solution

Since , out of 100, 52 adults consume 1 cup of coffee daily, then assuming that the employees of the University are all adults, out of 3750, the number of employees who drink 1 cup of coffee daily is (52/100)*3750 = 1950.

a. Apparently, 3750 -1950 = 1800 employees will not drink coffee for one day ( if we assume that the adults drink not more than 1 cup of coffee in a day).

b. Since the number of adults who drink 1 cup of coffee in a day is 1950, the number of cups of coffee sold in a day is 1950. Therefore, the number of cups of coffee sold in 5 days is 5*1950 = 9750. Hence the revenue generated by the coffee machine in a week(5 days) is $ 9750*0.95 = $ 9262.50.
