The Crispy Baking Company is considering the expansion of its business into door–to-door
delivery service. This would require an additional $12,500 in labor costs per month.
Company-owned vehicles now used to make morning deliveries to restaurants could be
used in the afternoons to make the home deliveries. However, it is estimated that an
additional $5,000 would be required per month for gas, oil, and maintenance. It is further
estimated that the home delivery use of the trucks would be allocated 45% of the existing
$6,500 fixed vehicle costs. What is the differential delivery cost per month for expanding
into the home delivery market?
