    Mr. Demerath has a large collection of Hawaiian shirts. He currently has 42 Hawaiian shirts. He gets 2 more every month. After how many months will Mr. Demerath have at least 65 Hawaiian shirts?

    We set up the function H(m) where m is the number of months that goes by. Mr. Demerath's shirts are found by:
    H(m) = 2m + 42

    The problem asks for m when H(m) = 65. So we set H(m) = 65:
    2m + 42 = 65

    To solve this equation for m, we type it in our search engine and we get:
    m = 11.5
