A recent study found that one's earnings are affected by the mathematics courses one has taken. In particular, compared to someone making $$50,000$ who had taken no calculus, a comparable person who had taken $x$ years of calculus would be earning $$50,000e^{0\mathrm{.}195x}.$ Find the rate of change of this function at $x=1.($Round your answer to the nearest whole number.$)$ dollars per year per extra year of calculus
