#62# left

Explanation:

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.
