In the past year, a company paid US$60,000 to an external subcontractor for an ongoing project. The project manager has been asked to evaluate if the project can be delivered more cost effectively this year by using internal labor.

✑ Two engineers (monthly salary of US$700 each)
✑ One project manager (monthly salary of US$1,600)
✑ Additional estimated monthly expenses of US$2,000
