Caroline packs 12 jars of jam in a box. She has 40 boxes. She has 542 jars of jam. How many jars of jam will she have left when all the boxes are full?

Answer 1

Kennedy Adams

#62# left

First figure out how many jars the boxes can hold, then figure out how many extra she has.

She has #40# boxes that can hold #12# jars each, so the total number of jars that the boxes can hold are:

#40 xx 12 = 480# #"jars"#

But she has #542# jars, so how many will be left over? Subtract:

#542 - 480 = 62#

She will have #62# jars of jam left after all the boxes are full.
