Fixed earning - $2,456.75
Variable earning - $4.75x ; where x is the number of new gym membership he sold. It is a variable component because its value varies on the number of new gym membership sold increasing in the fixed factor of 4.75
Since the value of x is stated in the problem, the solution would be:
Fixed earning + Variable earning = Total Earning
2,456.75 + 4.75(32) = 2,456.75 + 152 = $2,605.75 - Krego's earnings last month.
