    I'm confused on how to make equations for problems like #1 on Problem Set 6A.
    I don't know how to form 2 equations, but only one.

    *Cont.
    Like in the problems such as "you earned $186. The t-shirts were 5 more that the sweatshits times 2."

    OK good, that's actually the harder one.

    can you write an equation to show the total number of fans in attendance?

    Umm...
    531=x+y?

    Yup... or better yet... x+y=531

    So now, those two equations form your pathetic little world... NO OTHER INFORMATION EXISTS.

    You can graph them both, right? (Go ahead and do it)

    For the money equation I got the slope -3/5, is that right? How would I try to graph that?

    One last thing-- is the intersection of the lines the solution? For this type of problem?

    Mr.C, for now, could I just please graph the equations in the packet? I'm running a little late..
    Instead of checking them on the online calculator, which I really don't know how to use..?
