Answer: e. both b and c
Step-by-step explanation:
Van delivered 600 per week and cost $400.
The cost per package for the Van is;
= 600/400
= $1.5 per package
Employees delivered 500 and cost $300 which means the cost per package is;
= 500/300
= $1.67 per package.
The results show that it costs more to deliver with Employees ($1.67) than with the Vans ($1.5). Using more Vans will therefore allow for more packages to be delivered using a fixed budget as the last dollar spent on Vans gave more output than the last dollar spent on Employees.
