The first option is wrong because you make 30 meatballs in 30 mins but then 30 meatballs in 20 mins. If it was constant then in 20 mins you make less meatballs.
The last option is wrong because if bacteria triples, then that is exponential, not constant change.
Only the middle option makes sense. The rate of change is $35 for each hour!

In the first scenario, the time it takes to makes the meatballs decreases.It takes 30 min at first to make 30 meatballs, then it take 20 minutes to make 30 meatballs.
In the second scenario, the amount of money the electrician is making per hour is constant.The electrician makes exactly $35 every hour.
The third scenario is an exponential graph. It will exponenitally increase because the bacteria will triple.
