Ответ:
Student C is correct.
Students A and B do not account for the variable in the equation. Student A assumes that it has already been 10 months when it has not been stated in the question. Student B has come to the conclusion that it has been 11 months. Neither have an equation to show for it. Student D is incorrect because the variable "m" equals the number of months, and the number of months would not equal the amount of money Walter would be receiving in total. Student C is correct because the variable "m", or months, is being multiplied by 200, or the amount of money.
For example, if 5 months were to pass, then you would receive 1000 dollars, because 5×200 is 1000. This would hold up, as in the original problem, you receive 200 dollars per month. another example is if you replace "m" with 0, then it will show that in 0 months, you will have 0 dollars, and it is stated at the beginning of the problem that Walter's bank account starts at $0.

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
