Answer:
and
Step-by-step explanation:
We have been given the parabola with vertex (1, -9) and y intercept at (0, -6).
Now we need to find the x-intercepts of that parabola. So first we begin by finding the equation of parabola using vertex formula:
Vertex for this formula is given by (h,k)
Compare that with given vertex (1,-9), we get: h=1, k=-9
So plug these into vertex formula:
...(i)
Plug given point (0, -6). into (i)
Plug a=3 into (i)
Now to find x-intercept, we just plug y=0 and solve for x
Hence final answer are
and
775-550 = 225 for an extra 15 guests
225/15= 15$ per person
