The link above is the question with a picture under it, I am having trouble with these word questions, but I can do regular questions that give you the equation and ask you to get the roots. My problem is reading a word problem and having to create an equation myself, I have always been bad at this...

All I could come up with was 100m^2 + 30m + 3 = 0

I know it is probably wrong...

Any help would be great. Thanks!
