a pound of popcorn is popped for a class party. the popped corn is put into small popcorn boxes that each hold 120 popped kernels. there are 1,450 kernels in a pound of unpopped popcorn. if all boxes are filled except for the last box, how many boxes are needed and how many popped kernels are in the last partially filled box?
First, calculate the total number of boxes needed to hold the popped corn:
1450 kernels รท 120 kernels per box = 12.08 boxes
Since you cannot have a fraction of a box, you will need to round up to the nearest whole number. Therefore, you will need 13 boxes in total.
To determine how many popped kernels are in the last partially filled box, subtract the number of kernels in the first 12 boxes from the total number of popped kernels in the pound:
12 boxes * 120 kernels per box = 1440 kernels
1450 total kernels - 1440 kernels in 12 boxes = 10 kernels
Therefore, the last partially filled box will have 10 popped kernels.
