The number of hours is the independent variable. The total cost of the surf lesson and surfboard is the dependent variable.
The function for the total cost of the surf lesson and surfboard rental can be written as:
C(x) = 2.50x + 65
Where C(x) represents the total cost, x represents the number of hours.
The independent variable in this scenario is the number of hours Mrs. Beckner uses the surfboard, denoted as "x".
The dependent variable is the total cost of the surf lesson and surfboard rental, denoted as "y".
The function for calculating the total cost, denoted as "f(x)", is as follows:
f(x) = 65 + 2.50x
where the initial fee of $65 is added to the product of $2.50 multiplied by the number of hours used.
The independent variable in this scenario is the number of hours, as it is what we can adjust or change.
The dependent variable is the total cost of the surf lesson and surfboard rental since it depends on the number of hours.
We can write a function to calculate the total cost as follows:
Total cost = $65 (initial fee) + ($2.50 * number of hours)
So the function for the total cost of the surf lesson and surfboard rental would be:
C(x) = $65 + ($2.50 * x)
In this function, "x" represents the number of hours Mrs. Beckner plans to use the surfboard. By substituting the value of "x" into the function, we can calculate the total cost.
