A survey of Town X found a mean of 3.2 persons per household and a mean of 1.2 televisions per household. If 48,000 people live in Town X, how many televisions are in Town X?

Please Show the work. Your effort is much appreciated.

    Number of households is 48,000/3.2

    => 15,000

    so, number of T.V.'s is 15,000 x 1.2

    i.e. 18,000 in total

    3.2/1.2=48000/x

    You cross multiply and get

    3.2x=57,600

    Then divide both sides, by x

    X = 18000

    So town x has 18,000 televisions

    so 4800 people live in town x, and 3.2 live in a house, there are 4800/3.2, or 1500, houses. there are 1.2 TVs per house, so there are 1500*1.2, or 1800 tvs.

    EDIT. my bad, 18000.
