(To find the average, divide the sum by the number of addends.) -What does the sentence in the parentheses mean? do you have to find it by adding all the addends that equals to the number, then divide it by the sum?

    Yes.

    Add the bills. Then divide by 5 to find the average.

    I added it, it was equal to $843.15, and when i divided it, the exact anser is... $168.63.

    in other words it wants you to find the average which is
    average = add all sums /number of sums
    this is how you will get your average.
    average=157.60+182.09+175.15+166.27+162.04/5
    =843.15/5
    =168.63
    so your answer is $168.63
