We examine the average order of some arithmetic functions written as sums over Euler function in arithmetic progression and in general over

such that

is a prime number,

an integer and

is a polynomial function with integer coefficients and a degree

that is not constant modulo

Our results are based on various estimates of rational exponential sums with the Euler Function in arithmetic progression which are due to William Banks and Igor E. Shparlinski.
