Answer:
C = 100 + 40n
The independent variable is n (number of months) and the dependent variable is C ( total cost)
Step-by-step explanation:
Let the total cost of the fitness center = C
Given fixed cost = $100
given cost per month = $40
let number of month = n
The total cost of the fitness center in a given 'n' month is calculated as;
C = 100 + 40n
From the above equation;
the independent variable is n (number of months) and
the dependent variable is C ( total cost)
