Studdy Solution
STEP 1
Assumptions1. The snowboard rental fee is 4.25.
3. The cost function, denoted as , represents the total cost of renting a snowboard for hours.
STEP 2
We need to write a linear cost function for the given situation. A linear function has the form , where is the slope (rate of change), is the independent variable, and is the y-intercept (initial value).
In this case, the cost per hour (t20) is the initial value.
So, the cost function can be written as
STEP 3
Now, let's identify all variables used in the cost function.
1. This is the dependent variable, representing the total cost of renting a snowboard for hours.
2. : This is the independent variable, representing the number of hours the snowboard is rented.
Given the options, the correct answer is. represents the cost of renting a snowboard for hours.
