Given the functions \( f(x) = 2x + 3 \) and \( g(x) = 3x - 2 \), if Emma buys \( n \) items at $2 each and \( m \) items at $1.5 each, and she spends \( P \) dollars in total. For \( n = f(g(3)) \) and \( m = g(f(2)) \), compute the total number of items Emma buys and the total amount she spends on these items. Then, determine how much more or less she spends compared to \( P = 50 \) dollars. Let's think step by step and output the final answer within \boxed{}.
