Answer

Solution

The cost of 2.5 pounds of cheese is $5.60. From the given data we can find the cost of 1 pounds of cheese.

The cost of 1 pounds of cheese =  $5.60./2.5 =2.24

Mrs Peterson bought 9 pounds of cheese for her deli

we need to find cost of 9 pounds of cheese .

So she spends total = 2.24 x 9 = $20.16

No. of Persons= 16

Step-by-step explanation:

There was a one phone line

Average no of people calling = 60 in one hour

% of all callers at most can get busy signal

Probability < 0.6

Probability for less than 1 person on hold = 0.2642

No of persons = 0.2642(60)

= 15.852 or 16

16 persons in hour the company is able to put on hold
