    Answer:

    1431 total strings of lights.

    Step-by-step explanation:

    First, we need to set up a proportion for this problem.

        480 deficient             =             162 deficient  

          4,240 total                                 x total

    use the “butterfly” method: multiply each diagonal of the proportion and set them equal to each other.

    162 * 4,240  =   480x

    686880 =   480x

    686880/480 =  x

    x = 1431 total strings of lights.
