a.
To write: an equation according to the given question
a.
Answer to Problem 50PPS
The required equation is:
Explanation of Solution
Given:
The charges for admission before 6 P.M are $70.
The charges for admission after 6 P.M are $25.
Total charges on Saturday: $28,000
Calculation:
Let suppose,
The total number of admissions before 6 P.M were x.
The total number of admissions after 6 P.M were y.
On Saturday, the total collection of the amusement park was $28000.
Hence, the collection before 6 P.M
The collection after 6 P.M
Therefore, the equation will be,
Conclusion:
The equation is
b.
To graph the equation acquired in sub-part a. which is
b.
Explanation of Solution
Given:
The equation is:
Calculation for graph:
Consider
Values of x | Values of y |
0 | 400 |
1 | 399.64 |
-1 | 400.35 |
2 | 399.28 |
-2 | 400.71 |
By taking different values of x , the graph can be plotted.
Graph:
c.
To find: the x and y intercepts and explain them.
c.
Answer to Problem 50PPS
x- intercept = 400
y- intercept = 1120
Explanation of Solution
The equation is:
Graph:
Interpretation:
x - intercept: The graph intersects the x -axis at
y - intercept: The graph intersects the y-axis at about
Conclusion:
Hence, x − intercept = 400 and y - intercept = 1120.
