Answer to Problem 8CB
Independent variable is the number of concert tickets and dependent variable is the cost of the tickets.
Explanation of Solution
Given:
A person J buys a concert ticket for himself and his friends. If he buys more concert tickets, the cost is greater.
Calculation:
It is given that a person J buys a concert ticket for himself and his friends. This means that the cost of the tickets is same for all.
Now, the person J buys more concert tickets, and then the cost is greater. This implies that the cost increases as the number of tickets is more.
Therefore, the cost of tickets is dependent variable where as the number of concert tickets is independent variable as it can be increase or decrease.
Thus, the independent variable is the number of concert tickets and dependent variable is the cost of the tickets.
