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 1,600 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 partially filled box?

Using modulus calculator, we know 1600 mod 120 gives us 13 full boxes of unpopped popcorn.

We also know that 13*120 = 1,560. Which means we have 1,600 - 1,560 = 40 popped kernels left in the last box.
