D, B, C, A

Step-by-step explanation:

D is the x coordinate of the vertex of the function because the greatest daily profit means the vertex of the parabola. and since x represents price, the answer is D

B is the y coordinate of the vertex of the function because the max profit means you are looking for the highest or lowest point of the parabola. And since the leading coefficient is -10, that means the opening is downward and there is a max, not min value.

if the make no money ($0 daily profit) which is the y value, that means you are looking for the x-int. This is because x-int if when y = 0. the answer is c

y int is when x is 0, so the answer is A
