I can't figure out number 28 on the math portion of the Marine Gouge for some reason. Here's the question:
At a "mess night" there are only captains, 2nd lieutenants, and 1st lieutenants. If the total number of 2nd lieutenants and 1st lieutenants is 30, the total number of 2nd lieutenants and captains is 45, and the total number of 1st lieutenants and captains is 35, what is the total number of company grade officers at the mess night?
All that I need is the formula on how to do a problem like this. I haven't taken a Math class since '01 and my test is coming up. This is the only question that I'm having trouble with and if I get this I will feel pretty good going into the test. Thanks again, this website is a life-saver!
