Angelo works as an engineer earning a salary of $120 000 per year (after taxes). He has been thinking about taking a one-year leave of absence from his job to volunteer with an environmental nonprofit organization in Australia. The $3 500 round trip cost of travelling to Australia would have to be paid by Angelo. While volunteering, his living expenses would fall by $300 per month as the organization is willing to pay part of the expenses. What would be the opportunity cost of volunteering for one year if we consider only monetary costs and not any intrinsic value of the
experience to Angelo?
