Question

In this exercise, you create a program for the sales manager at Computer Haven, a
small business that offers motivational seminars to local companies. Figure 7-53 shows
the charge for attending a seminar. Notice that the charge per person depends on the
number of people the company registers. For example, the cost for four registrants
is
$400; the cost for two registrants is $300. The program should allow the sales manager
to enter the number of registrants for as many companies as needed. When the sales
manager has finished entering the data, the program should calculate and display the
total number of people registered, the total charge for those registrants, and the average
charge per registrant. For example, if one company registers four people and another
company registers two people, the total number of people registered is six, the total
charge is $700, and the average charge per registrant
is $116.67.
Number of people a company registers Charge per person ($)
1 – 3 150
4 – 9 100
10 or more 90
Figure 7-53
a. Create an IPO chart for the problem, and then desk-check the algorithm appropriately. and . List the input, processing, and output items, as well as the algorithm, in a chart similar
to the one shown earlier in Figure 7-42. Then code the algorithm into a program.

please provide ipo chart and algorithm. thank you C++

PLEASE GIVE IT A THUMBS UP, I SERIOUSLY NEED ONE, IF YOU NEED ANY MODIFICATION THEN LET ME KNOW, I WILL DO IT FOR YOU
