The interval that best represents the number of meals Franco's Hotdogs can sell and make a profit is (2, 18).
This can be seen from the graph, which shows that Franco's Hotdogs can
sell between 2 and 18 meals per day and make a profit.
If Franco's Hotdogs sells fewer than 2 meals, they will lose money.
If they sell more than 18 meals, they will also lose money, because the cost
of producing each additional meal will be greater than the revenue
generated from selling that meal.
The other answer choices are incorrect:
(0, 10): Franco's Hotdogs cannot sell 0 meals and make a profit.
(0, 200): Franco's Hotdogs cannot sell 200 meals in a day.
(2, 10): Franco's Hotdogs can sell more than 10 meals and make a profit.
Therefore, the correct answer is (2, 18).
