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 1450 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?

Answer 1

Answer: 12 boxes.

20 kernels in the last box.

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

Answer 2

12 boxes are needed

Last box contain only 20 kernels

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
