    SAT reasoning

    A clothing manufacturer has determined that she can sell 100 suits a week at a selling price of $200 each. For each rise of $4 in the selling price she will sell 2 less suit a week. If she sells the suits for $x each, how many dollars a week will she received from sales of the suits?

    How could I solve this?

    suits sold = 100 - [2(x - 200)] / 4 = 100 - (x - 200) / 2 = (400 - x) / 2

    wrap it up!

    Btw, that takes care of similar $4 reductions in selling price (2 more sold for each $4 reduction.
