Answer:
A. $12
Step-by-step explanation:
For a quadratic of the form ax²+bx+c, the axis of symmetry is given by ...
x=-b/(2a)
For your quadratic function, the axis of symmetry is ...
s = -(2400)/(2(-100)) = 12
The function has its extreme value on the axis of symmetry. Here, the leading coefficient is negative, so the parabola opens downward. That means the extreme value is a maximum.
Profit will be a maximum at a selling price of $12.
Answer:
300 cupcakes
Step-by-step explanation:
Okay, the first step is finding 25% of 240, we do this by multiplying .25 by 240. This gets us 60. Then, to get 125% of 240 (since sales dropped 25%), we add 240 and 60, this gets us 300. 300 cupcakes were sold. Another way to do this is 1.25x240. I wanted to explain it more thoroughly, though.
Since all reflections are inverse of itself, carrying any reflection about the same axis twice will carry the preimage back to itself.

67 multiplied by 3 is 201, so there is 201 people in the age group 12-29. Also, 67% is approximately two thirds, and we can see that reflected in our answer.
