Question

The sales S (in thousands of units of a new CD burner after it has been on the market t years are modeled by S(t)=100(1-e^kt). Fifteen thousand units of the new product were sold in the first year. a) Complete the model by solving for k. b) Sketch the graph of the model. c) Use the model to estimate the number of units sold after 5 years.

Answer 1

S=15. Divide 15 by 100 and rearrange equation so e is at the other side. Use log of e then
