After an advertising campaign, a company’s marginal profit was adjusted up from M₁(x) = 2x² - 3x + 11, before advertising, to M₂(x) = 2x² - 2.4x + 8, after advertising. Here x denotes the number of units produced, and M₁(x) and M₂(x) are measured in thousands of dollars per unit. Determine the net change in profit that resulted from increasing the production level from x = 5 to x = 10 due to the advertising campaign.
