Solve the following.
If R(X) = 36x + 3x² + 5 then find actual revenue from selling 50th item.
If $R(X) = 36x + 3x^2 + 5$ then find actual revenue from selling 50th item.
Answer
Answer
Revenue from the 50th item $= R(50) - R(49)$.
$R(50) = 36(50) + 3(50)^2 + 5 = 9305$
$R(49) = 36(49) + 3(49)^2 + 5 = 8972$
$R(50) - R(49) = 333$
Final answer: 333
