A factory selling earphones has a marginal cost function MC(x) = 0.003x^2 - 3.387x + 387 and a marginal revenue function given by MR(x) = 387 - 3x, where x represents the number of earphones. MC(x) and MR(x) are in dollars per unit. Find the total profit, or area between the graphs of these curves, between x = 0 and the first intersection point of these curves with x > 0. Enter your answer in dollars, rounded to two decimal places if needed.
