Maria Pajet, a regional sales representative for UniTec Systems, Inc., has been working about 80 hours per week calling on a total of 123 regular customers each month. Because of family and health considerations, she has decided to reduce her hours to a maximum of 160 per month. Unfortunately, this cutback will require Maria to turn away some of her regular customers or, at least, serve them less frequently than once a month. Maria has developed the following information to assist her in determining how to best allocate time:

Customer Classification

Large Business Small Business Individual
# of Customers 8 35 80
Average Monthly Sales p/Customer $2,500 $1,500 $600
Commission Percentage 5% 8% 10%
Hours per Customer per monthly visit 5.0 3.0 2.5

Required

Develop a monthly plan that indicates the number of customers Maria should call on in each classification to maximize her monthly sales commissions.
