Answer: It is sixty four-64
Answer:
2. either of two angles whose sum is 180°.
3. each of the pairs of opposite angles made by two intersecting lines.
4. Two angles are adjacent when they have a common side and a common vertex (corner point) and don't overlap.
5. The acute angle is an angle less than 90°
6. It is more than 90° and less than 180°.
7. an angle of 90°
8. an angle of 180°
We can write that as a function:
![f(n)=(200 -20n) * (300 + 50n)\\f(n)=60000+10000n-6000n-1000n^2\\f(n)=-1000n^2+4000n+60000\\](https://tex.z-dn.net/?f=f%28n%29%3D%28200%20-20n%29%20%2A%20%28300%20%2B%2050n%29%5C%5Cf%28n%29%3D60000%2B10000n-6000n-1000n%5E2%5C%5Cf%28n%29%3D-1000n%5E2%2B4000n%2B60000%5C%5C)
where
is the number of price reductions. We can see that it is a quadratic function which has the biggest value at P = (p, q). It means that p is the number of reductions which results in the biggest profit.
![p=\frac{-b}{2a}=\frac{-4000}{-2000}=2](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B-b%7D%7B2a%7D%3D%5Cfrac%7B-4000%7D%7B-2000%7D%3D2)
It means that it's the best to make 2 price reductions for the company. The tickets should be sold for $200 - 2 * $20 = $160. It results in 2 * 50 more tickets sold which is 300 + 100 = 400.
Answer:
Ticket price: $160
Number of tickets: 400
The answer is D minus 7 over 2.
