Question

Joes electric made 16 customer calls last week and 23 this week. How many calls must be made next week in order to maintain an average of at least 19 callable week for the three week period ?

Answer 1

To maintain an average of at least 19 calls per week over a three-week period:

x= total calls sought

Average=Total calls/Number of weeksAverage

19 ≤ x/3

19*3≤x

x ≤57

For an average of at least 19 calls per week over three weeks, the total number of calls should be at least 57. in 2 weeks he called 39 customers

For an average of at least 19 calls, he should call 57-39=18 customers in week 3.
