b^u=b^v, then u=v Name two exponential rules. Hint(We learned them in the beginning of the semester)
1) b^u=b^v, then u=v 2) b^-1=1/b

Weekly sales will drop rather quickly after the end of an advertising campaign. This drop in sales is known as sales decay. Suppose that the gross sales, S, in hundreds of dollars, of a certain product is given by the exponential function. S(t)=2000(3^-0.2t) Where t is the number of weeks after the end of the campaign. What was the level of sales immediately after the end when t=0? After 1 and 4 weeeks?

t(0)=2000 t(1)=1605 t(4)=830
