Lantz Family Restaurant operates in a suburb of a major city. Recently, the managers at Lantz have noticed an increase in the use of delivery apps such as Grubhub and DoorDash by their customers. The average fee paid by Lantz for this service currently is $6 per delivery. The managers are considering starting their own delivery service that they estimate would attract about 75 percent of the current deliveries. (Not all customers will switch, even though the service would be free, because of the convenience of the app, habit, and other factors.) Estimates by the financial consultant to Lantz are that the cost of the service, if provided by Lantz, would be $3.90 per delivery and an incremental $1,297 per month fixed costs. In an average month, 800 orders Lantz receives are to be delivered. Required: a. Prepare a schedule that shows the differential costs. b. Should Lantz Family Restaurant provide their own delivery service or continue to rely on other firms? Prepare a schedule that shows the differential costs. (Select option "higher" or "lowe base. Select "none" if there is no effect.)
