A company determines that its marginal revenue per day is given by R' ( t ) , where R ( t ) is the total accumulated revenue, in dollars, on the tth day. The company's marginal cost per day is given by C' ( t ) , where C ( t ) is the total accumulated cost, in dollars, on the tth day. R' ( t ) = 80 e t, R ( 0 ) = 0; C' ( t ) = 80 - 0.8t, C ( 0 ) = 0 Find the total profit P ( T ) from t = 0 to t = 10 ( the first 10 days ) . P ( T ) = R ( T ) - C ( T ) = [R' ( t ) - C' ( t ) ] dt The total profit is $ . ( Round to the nearest cent as needed. ) Find the average daily profit for the first 10 days. The average daily profit is $ . ( Round to the nearest cent as needed. )
