Question

To the nearest dollar, what does the analyst believe the value of the stock will be at the end of three weeks? (Note: Disregard the $ sign when gridding your answer.)

Answer 1

Since the stock value loses $28$ percent every week, it will be $100-28=72$ % every week.
Thus, $r=0.72$
Thus, the equation $V=360(r{)}^t$ will be $V=360(0.72{)}^t$
After $3$ weeks, $V=360(0.72{)}^3=134.47=134$
