A new cell phone is introduced into the market. It is predicted that sales will grow logistically. The manufacturer estimates that they can sell a maximum of 100 thousand cell phones. After 42 thousand cell phones have been sold, sales are increasing by 2 thousand phones per month. Find the differential equation describing the cell phone sales, where y(t) is the number of cell phones (in thousands) sold after t months. dy dt Enter at least 3 decimal places for the constants.
