How do I set up this problem? If a person works 35 hours/week and earns $450, how much will he get for working 50 hours? 35/450 = 50/x ?

    There are multiple ways to set up any proportion problem. Yours works.

    Personally, I like the variable in the numerator. It saves a step in the solution process. Just multiply by the denominator number to solve.
    .. x/450 = 50/35 ... ratio of dollars = ratio of hours
    .. x/50 = 450/35 ... dollars per hour = dollars per hour

    You can also put the variable in the denominator.
    .. 35/450 = 50/x ... hours per dollar = hours per dollar (your version)
    .. 450/x = 35/50 ... ratio of dollars = ratio of hours
    After you work a few of these, you will recognize the solution is always
    .. x = 50*450/35 ... hours * (dollars/hour) = dollars

  2. Como

    50/35 x $450

    10/7 x $450

    $4500 / 7 = $ 643_____to nearest whole number

    x/50 = 450/35
    --->x = 450*50/35 = ...calculator
