Question 11

Draw a flowchart to read the sales representative file of a major company, which includes:

• Representative number (N),
• Sales amount (A),
• Representative name (M),
  Calculate the sales commission at 2.5% for sales less than 50,000 pounds, and 5.5% for sales above that amount. Print lists that include the representative number, sales amount, commission value, and representative name. The lists end with the total sales amount and the total commission value for the sales representative.

Algorithm

Start
Assign totalSales = 0, totalCommission = 0
Read N # Representative Number
While N != 555:
  Read M, A # Name (M), Sales Amount (A)

  IF A < 50000:
    Assign commission = A * 0.025
  Else:
    commission = A * 0.055

  Print N, M, A, commission
  Assign totalSales += A
  Assign totalCommission += commission
  Read N # Next Representative Number

Print totalSales, totalCommission
End
