Question

33 multiple choice 1 point joe paid $400 to join a workout team. he pays an addition $20 every time he uses the clubs workout facilities. choose the equation that describes joes total cost for working out as a function of the number of times he works out. \\( c = 400 - 20n \\) \\( c = 400n + 20 \\) \\( c= 20n + 400 \\) \\( c = (20 + 400)n \\)

Explanation:

Step1: Define Variables

Let \( n \) be the number of times Joe works out, and \( C \) be the total cost.

Step2: Analyze Fixed and Variable Costs

The fixed cost (one - time cost to join) is $400. The variable cost is $20 per workout, so for \( n \) workouts, the variable cost is \( 20n \).

Step3: Formulate the Cost Function

Total cost \( C \) is the sum of fixed cost and variable cost. So \( C=20n + 400 \).

Answer:

C = 20n + 400 (the third option)
