<h3>What is the equation that represents the cost of the gym membership?</h3>
The cost of gym membership is the sum of the fixed cost and the variable cost. The fixed cost is the start-up fee while the variable cost is the cost per month.
The equation that represents the cost of the gym membership is: c = $100 + $40m
Where m represents the number of months
The cost of 1 year membership = $100 + $40(12)
$100 + $480 = $580
