1. Your room-mate’s long hours in Chem lab finally paid off―she discovered a secret formula that lets people do an hour’s worth of studing in 5 minutes. So far, she’s sold 200 doses, and faces the following average-total-cost schedule:
Quantity Average Total Cost
199 $199
200 $200
201 $201
If a new customer offers to pay her $300 for one dose, should she make one more? Explain.
