Jerry works no more than 20 hours a week during the school year. he is paid $10 an hour for tutoring geometry students and $7 an hour for delivering pizzas for pizza king. he wants to spend at least 3 hours, but no more than 8 hours, a week tutoring. find jerry’s maximum weekly earnings.

Works no more than 20 hours/week

3-8 hours tutoring
Subtract 3-8 from the 20 to give you hours for pizza delivery

So anywhere between 12-17 hours for pizza delivery

To find his maximum weekly hours (keeping in no more than 20 hours)

3 hours tutoring
17 hours pizza

3 x $7 = $. $21
17 x $10 = $170

$191
If he did
8 hours of tutoring
12 hours of pizza

8 x &7 = $56
12 x $10 = $120

$176

So he'd be better off working more hours delivering pizza & less doing tutoring

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
