The marginal profit for a certain company is MP₁(x) = -x² + 14x - 24. The company expects the daily production level to rise from x = 6 to x = 8 units. The management is considering a plan that would have the effect of changing the marginal profit to M₂(x) = -x² + 12x - 20. Should the company adopt the plan? Determine the area between the graphs of the two marginal profit functions from x = 6 to x = 8. Interpret this area in economic terms.
