a.

Answer to Problem 32IP
The cost at Wild Waves is
Explanation of Solution
Given information:
The table shows the bus prices to travel to each park and the admission price per student.
The equation representing the cost at Wild Waves is:
The equation representing the cost at Coaster Haven is:
b.
To graph the equations.
b.

Explanation of Solution
Given information:
The given equations are:
The equation representing the cost at Wild Waves is
The equation representing the cost at Coaster Haven is
Graph:
Interpretation:
The lines seem to meet at
c.
To find which trip would cost less if the number of students are given.
c.

Answer to Problem 32IP
The trip at Wild Waves will cost less if
The trip at Coaster Haven will cost less if
Explanation of Solution
Given information:
The given statement is:
“If
The equations representing the cost for both the trips are:
Wild Waves:
Coaster Haven:
Calculation:
The cost for both the trips if
Hence, the trip at Wild Waves will cost less if
The cost for both the trips if
Hence, the trip at Coaster Haven will cost less if
d.
To state if the results of part c was possible by examining the graph in part b.
d.

Answer to Problem 32IP
The difference in slope of both the equations of the graph is very small, so both the lines appear to be together. But closely looking, it is evident that the cost of Coaster Haven will decrease if the number of students are more than
Explanation of Solution
Given information:
The graph obtained in part b is:
