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.

Total cost = 5000 + 500n
Total sessions attended = n * (1 + 1/10) = 11n/10
Average cost per session = (5000 + 500n) * 10 / (11n)
