Question

Tom and Jerry have to stuff and seal 50 envelopes for a new marketing campaign. Jerry can stuff and seal 7

envolpes alone in 2 minutes. Tom can do 4 envelopes per minute. Write the equation that can be used to find the number
of minutes (t) it takes Tom and Jerry to stuff and seal 50 envelopes together. Next find the number of minutes.

Answer 1

It takes them 7minutes to finish 50env

Explanation:

We know that jerry can stuff 7 in 2min and tom can do 4 per min, so 8 for every 2min.

So 8+7=15env for every 2min 7.5/min

15+15=30+15=45

50=15x/2 50*2=15x 100=15x 100/15=x x=6.67 then rounded it to 7min
