3. Suppose a new magazine initially sells 600 copies per month. Research indicates that a vigorous advertising campaign could increase sales by 40% each month if our market were unlimited. But research also indicates that magazine sales in our area are unlikely to exceed 2400 per month. Make a logistic model of projected magazine sales. a) N = 600 1+ 3e-03361 b) N = 2400 1+ 3e-03361 c) N = 40 1+ 3e -0.336t d) N = 2400 1+ 40e -0.336
