increase in x results in the decrease in y
Answer:
Step-by-step explanation:
Let x be the price increase.
<u>Then the current price is: </u>
<u>Then the number of passengers is:</u>
<u>Then the revenue: </u>
- Revenue = Price * Number of Passengers
- R = (50 + x)(8000 − 100x) =
- - 100x² + 3000x+ 400000
This is a quadratic relationship. Maximum point is obtained at vertex.
<u>Vertex is determined by x = - b/2a, find the value of x:</u>
- x = - 3000 / (-2*100) = 15
<u>The maximum revenue is:</u>
- R = (50 + 15)(8000 − 100 * 15) = 424500
Answer:

Step-by-step explanation:
Given
Cube and Spinner (See attachment for spinner)
Required
Find P(3 and C)
In the attached spinner, there are 8 partitions and C = 2
So:


In a number cube, there are 6 faces and 1 side is 3.
So:

P(3 and C) is calculated as:
