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

d is correct

step-by-step explanation:

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
