Answer 5

Oh, sorry. I forgot.

If that's how it is stated, one thing to do is to get the average rate of change for each pair of year. That is, find the values of \(\frac{1849-4300}{2-1}, \frac{795.07-1849}{3-2}, \frac{341.88-795.07}{4-3}\), and see which is largest among them.

Answer 6

oh, sorry again. Where are we? I just want to ask first under what topic is this problem? I am just confused how to approach the problem.

Answer 7

OK, seems that I have to use my approach first.

t 1 2 3 4
f(t) 4300 1849 795.07 341.88

First, analyze how the price of the product changes from t = 1 to t = 2. Notice at t = 1, the price is 4300, and for t = 2, the price is 1849. Thus, for a span of one year, the price changes by 4300 - 1849 = 2451, and thus the percentage decrease of change of price from t = 1 to t = 2 is 2451/4300 = 0.57 or 57%.
