Answer:
The maximum revenue is $900, obtained with 30 people
Step-by-step explanation:
Naturally, the answer should be a number equal or higher than 20, because up to 20 persons, each one pays the same. Lets define a revenue function for x greater than or equal to 20.
f(x) = x*(40-(x-20)) = -x²+60x
Note that f multiplies the number of persons by how much would they pay (here, assuming that there are more than 20).
f is quadratic with negative main coefficient and its maximum value will be reached at the vertex.
The value of the x coordinate of the vertex is -b/2a = -60/-2 = 30
for x = 30, f(x) = 30*(40-(30-20))=30*30=900
So the maximum revenue is $900.
No. For fractions to be equal, both the numerators and denominators have to be proportional.
Since both denominators are 2, the denominators would have to be just 3 or just 4.
0.000038 = 3.8e-5 = 3.8×10⁻⁵
Answer:
Sure. Whats the question.?
Step-by-step explanation:
63/84 divided by 21/21
=3/4
or
63 divided by 84=0.75 which is the same thing as 3/4
