    Answer: 12 boxes.

    20 kernels in the last box.

    Step-by-step explanation:

    Hi, to answer hits question, first we have to divide the total number of kernels in one pound (1450) by the number of kernels that each box holds (130).

    Mathematically speaking

    1450 / 130 = 11.15 boxes

    This means that 11 boxes can be fully filled, and one box will be not be fully filled.

    11+1 = 12 boxes needed

    So, the 12th box is no fully filled

    11.15boxes - 11 full boxes = 0.15 = 15% filled

    Since each box holds 130 kernels, we have to multiply that value by how much the last box can hold (15% in decimal form).

    130 x 15/100 = 19.5 ≅ 20 kernels

    In the last box there are 20 kernels

    12 boxes are needed

    Last box contain only 20 kernels

    Step-by-step explanation:

    It is given that,

    a pound of popcorn is popped for a class party.

    The popped corn is put into small popcorn boxes that each hold 130 popped kernels.

    There are 1450 kernels in a pound of unpopped popcorn.

    If all the boxes are filled except for the last box,

    To find the number of boxes

    number of boxes = Total number of kernels/Number of kernel in each box

    = 1450/130 = 11 2/13

    Therefore total number of boxes = 11 + 1 = 12 boxes

    number of kernels in 11 boxes = 11x 130 = 1430 kernels

    So last box contain = 1450 - 1430 = 20

    Last box have only 20 kernels
