Question

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 1,450 kernels in a pound of unpopped popcorn. If all the boxes are filled except for the last box, how many boxes are needed and how many popped kernels are in the last box? Please explain how you get the answer

Answer 1

12 boxes are needed and 20 will be in the last box.

1450/130 is 11.15 so You round up and need 12 boxes (because you can’t have .15 of a box) so you get the 11 boxes and multiply by how much it can hold (130) and get 1430 which is 20 short of 1450 so 20 would be in the last box .

Answer 2

Answer:

12 boxes are needed  in all.

Last box will contain only 20 kernels.

Step-by-step explanation:

Given is :

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

There are 1450 kernels in a pound of un popped popcorn.

If all the boxes are filled except for the last box, then how many boxes are needed?

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

=> $\frac{1450}{130}= 11.15$

Therefore, a total of 11+1 = 12 boxes are needed as 11.15 is more than 11.

And the last box will contain = $1450-1430=20$ kernels.

Therefore, the last box will have 20 kernels.
