Question 1058140: I'm not sure if I'm setting it up correctly I know you use the P(t)=Pob^t
so is it P(3)= 1200(1-0.15)^t ?

a. The computer you want cost $1200 when it first came out on the market but after 3 months the price was reduced by 15%. What was was the price then?
b. If the price falls by another 15% next month, what will the price be then?

You can put this solution on YOUR website!
Your basic format and equation model look good but change just so the appearance is like this: P%28t%29=P%5Bo%5Db%5Et as your format, and the model you are picking is P%28t%29=1200%2A%280.85%29%5Et. Click the Show Source link to see what the code being formatted looks like.

Be careful how you use the model. What is t? Is this to be years, months, quarter of a year? Your exercise may be easier to just ignore the Exponential Decay idea, and just use percents. An exponential function is not needed here.

(a)
1200%2A%280.85%29=1020--------the 15% reduction new price after three months.

(b)
Fifteen percent reduction BASED ON WHAT?

(c)
Need to know what (b) means, first.
