IF SOMEONE HELPS ME I WILL LOVE THEM FOREVER

The price of products may increase due to inflation and decrease due to depreciation. Derek is studying the change in the price of two products, A and B, over time.
The price f(x), in dollars, of product A after x years is represented by the function below:
f(x) = 12500(0.82)x

Part A: Is the price of product A increasing or decreasing and by what percentage per year? Justify your answer.

Part B: The table below shows the price f(t), in dollars, of product B after t years:
t (number of years) 1 2 3 4
f(t) (price in dollars) 5600 3136 1756.16 983.45

Which product recorded a greater percentage change in price over the previous year? Justify your answer.

Answer 1

Part A: for product A would be decreasing I would say by about 18% every year. And 82 would be the percentage left after the years.

Part B: for product B there is a much larger change because before it had a difference in percentage by 44%. And product A only had a difference in percentage by 18%.
