Hi,
You stuffed 108 envelopes in 45 minutes. {{{ 45/60 = (3/4)hr}}}
At this rate how many{{{highlight(x)}}} envelopes can you stuff in 2 hours.
Inquiry Sets Up the proportion:
{{{ (3/4)/108 = 2/x}}}}   Cross Multiply to solve  for x
     (3/4)x = 216
          x = 216(4/3) = 288 envelopes can be stuffed in 2 hours.
