independent variable
input function
function
dependent variable
The number of hours is the dependent variable.
The total cost of the surf lesson and surfboard is the function.
The number of hours is the independent variable, and the total cost of the surf lesson and surfboard is the dependent variable.
In this scenario, the number of hours represents the independent variable. The independent variable is the variable that is controlled or manipulated in an experiment or situation. In this case, Mrs. Beckner can choose how many hours she wants to use the surfboard.
The total cost of the surf lesson and surfboard represents the dependent variable. The dependent variable is the variable that changes as a result of the independent variable. In this case, the total cost depends on the number of hours Mrs. Beckner uses the surfboard.
Now, let's break down the pricing structure to understand how to calculate the total cost.
The Surf Hut company charges an initial fee of $65 for the lesson, which is a fixed cost and does not depend on the number of hours.
In addition to the initial fee, there is a variable cost of $2.50 for each hour Mrs. Beckner uses the surfboard. This cost increases linearly with the number of hours she spends using the surfboard.
To calculate the total cost, you would multiply the number of hours Mrs. Beckner uses the surfboard by $2.50 and then add the initial fee of $65.
