Question

The cost of a ticket is $7. write an equation that relates to the total cost/c, for a particular number of tickets purchased. Identify the independent and dependent variables.

Answer 1

If we know the cost of a ticket is $7, we can then write an equation in slope-intercept form for the amount it will cost to buy any amount of tickets.

If we denote x as the amount of tickets purchased, and c as the total cost, we can write the equation:


`c=7x`

Since we can vary the amount of tickets purchased independently of the total amount, x (the amount of tickets purchased) will be the independent variable.

However, since y (the total cost) is directly dependent on the amount of tickets that are purchased, c is the dependent variable.
