Answer:
Third option

Step-by-step explanation:
In this case we must write a quadratic equation in the vertex form.
We have the vertice. (-1, 5)
We know that the vertex form for a quadratic equation is:
.
Where (h, k) is the vertex.
So if the vertex is (-1, 5), the equation sought is:


Therefore the answer is the Third option.
Answer:
a) 720
b) 60$
Step-by-step explanation:
a) each person is served 3 pancakes and there are 240 people, 240 x 3 = 720.
b) Each bag of mix costs 10$ and can make 120 pancakes, but we need 720 pancakes, which means six bags of mix (since 120x6 = 720). Since each cost 10$, 10 x 6 = 60$
