Based on your response, that doesn't make sense. The question is asking for Total Project Overhead. How do you get 3600.00? Here is the entire question. What is the total project overhead for a project that lasts 3 months and has the following costs? Labor is $4,000; materials are $9,500; equipment rentals are $1,200; superintendent's annual salary is $36,000; office rent is $800 per month; and office utilities are $375 per month. What is the mathematical equation and explanation, please.
