Sheldon is the only landscaper in town. To keep things simple, he only mows lawns. Assume he has five possible customers with different willingness to pay for a month of lawn service as depicted in the table below. Customer Willingness to pay (WTP) for a month of lawn service $120 2 $100 3 $80 4 $60 5 $40 Suppose Sheldon has variable costs of $38 per customer and fixed costs of $130. Sheldon must charge each customer the same price, so he needs to decide whether to charge $120, $100, $80, etc. If Sheldon maximizes his profit, he will earn $ (if there are losses, include the negative sign)
