Answer:
13 jobs
Explanation:
if 40 dollars are made for 5 jobs you have to find what was made for one job which is 8 dollars
then you have to divide 100 by the 8 to find how many 8 dollar jobs it will take to make the 100 dollars.
you get 12.5 whuch beace you cant do half a job, you round it up to 13 jobs.
