Barry's Bar-B Quo is a popular lunch time spot. Barry is conscientious about the quality of his meals, and he has a regular crowd of 400 patrons for his $9.20 lunch. His variable cost for each meal is about $2.70, and he figures his fixed costs, on a daily basis, at about $1, 900. From time to time, bus tour groups with 50 patrons slop by. He has welcomed them since he has capacity to seat 500 diners in the average lunch period, and his cooking and wait staff can easily handle the additional load. The tour operator generally pays for the entire group on a single check to save the wait staff and cashier the additional time. Due to competitive conditions in the tour business, the operator is now asking Barry to lower the price to $4.20 per meal for each of the 50 bus tour members. (Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places.) Required: What is the net benefit (cost) if Barry accept the $4.20 price
