The Robinsón's electric bills for the last five months have been $157.60, $182.09, $175.15, $166.27, and $162.04. Find the average of the bill. (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?

    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
