We can let the number of P units sold = n and the number of Q units sold = 2n, and thus:
[(20 x n) + (17 x 2n)]/(n + 2n)(20n + 34n)/3n
54n/3n = $18.00
Quick solution: Imagine that he sold just 2 units of Q and 1 of P. His revenue would then be
Revenue = 2 x 17 + 1 x 20 = 54.
The arithmetic average for the 3 items sold would then be 54/3 = 18.
