Question

1. The probability of sales of pumpkin pies on the day before Thanksgiving holiday is as follows:

• 600 pies: 0.10

• 700 pies: 0.20

• 800 pies: 0.15

• 900 pies: 0.25

• 1000 pies: 0.15

• 1100 pies:0.15

Each pie costs $7 to make, and sells for $15. If the pies don’t sell, the excess is donated to a food shelter, netting a $2/pie tax break. How many pies should you order?
