he Crispy Baking Company is considering the expansion of its business into door$-$to$-$door delivery service. This would require an additional $$13,100$ in labor costs per month. Company$-$owned vehicles now used to make morning deliveries to restaurants could be used in the afternoons to make the home deliveries. However, it is estimated that an additional $$5,600$ 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 $50\%$ of the existing $$6,500$ fixed vehicle costs. What is the differential delivery cost per month for expanding into the home delivery market?TTT
