Mrs. Beckner is going to Hawaii. She plans to learn to surf. The Surf Hut company charges an initial fee of $65 for the lesson plus $2.50 for each hour she uses the surfboard.
The number of hours is the ____ (dependent variable, independent variable, function, input function) The total cost of the surf lesson and surfboard is the ____ (dependent variable, independent variable, function, input function).
The number of hours is the independent variable.
The total cost of the surf lesson and surfboard is the dependent variable.
The number of hours is the independent variable. This is because it is within Mrs. Beckner's control and she can choose how many hours she wants to use the surfboard for.
The total cost of the surf lesson and surfboard is the dependent variable. This is because it depends on the number of hours Mrs. Beckner decides to use the surfboard for. The total cost changes based on the number of hours used.
To calculate the total cost for the surf lesson and surfboard, you would need to add the initial fee of $65 to the product of the number of hours and the cost per hour ($2.50). This would give you the total cost as a function of the number of hours.
