A package delivery service uses vans and employees to deliver the maximum number of packages given a fixed budget. The last van added 600 packages to total output, while the last employee added 500 packages. If vans cost exist400 per week and employees earn exist300 per firm:. a. could deliver more packages with the same budget by using more employees and fewer Vans
b. could deliver more packages the same budget by using more vans and fewer with employees
c. use more vans and fewer employees because the last dollars spent on vans added more to total output than the last dollar spent on employees
d. is delivering the maximum number of packages given the fixed budget
e. both b and c

e. both b and c

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.
