Question

a) You are an engineering sales manager and are analyzing your sales data in your rapidly expanding communications company. After plotting the first six months of sales data after the product launch of your company's new model of cell phone, you find a curve that fits the data well: sales = 3 * month_since_launch^2. Your boss asks you to predict when you will hit 2000 total sales. Assuming that your sales continue to grow quadratically & fit the initial curve data, predict the number of months required to reach this milestone.

Assuming that your sales continue to grow quadratically & fit the initial curve data, predict the number of total sales that your company will have after the first 20 months.

Explanation / Answer

a) sales=2000=3*x^2 implies x=sqrt(2000/3)=25.8months since the launch

that is, approximately 26-8=18 months from now

b)after first 20 months, sales=3*20^2=1200
