Question

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

Answer 1

Answer:

It takes them 7minutes to finish 50env

Step-by-step 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
