define the unknown value and assign it to a variable ​

Answer 1

total_cost = $105

Explanation:

The unknown value in this scenario is the total cost that Sara and her friends paid for the skydiving lessons, including the charge per person and the tip given to the instructor. To assign this unknown value to a variable, let's call it "total_cost."

We can calculate the total cost by adding the charge per person and the tip given to the instructor. In this case, the charge per person is $75, and the tip given to the instructor is $30. Therefore, the total cost can be calculated as:

total_cost = charge per person + tip

total_cost = $75 + $30

total_cost = $105

So, the unknown value "total_cost" is equal to $105.
