Question 718638: Professor Smith teaches two sections of business statistics, which combined will result in 120 final exams to be graded. Professor Smith has two graduate assistants, Brad and Sara who will grade the final exams. There is a 3 day period between the time the exam is administered and when the final grades must be posted. During this time Brad has 12 hours available and Sara has 10. It takes Brad 7.2 minutes to grad and exam and Sara 12 minutes. Brad's will have 10% errors and Sara will have 6% that has to be regraded. How many exams should be assigned to each to minimize the number to be regraded. Solve in Excel. Formulate a linear programming model and graphical analysis.

REGRADING:R=1X1+.06X2
X1+X2=120
7.2X1<=720
12X2<=600
