To join a dance lesson, you paid a one-time membership fee of $5 000, then $500 for every session. If they gave you one free session after every ten sessions and you only have attended a number of paid sessions that is a multiple of 10, determine the function that represents the average cost per session and identify if the function is a rational function.
