Part a)  product a is decreasing by 18% per year1 - .18 = .82part b)  which product recorded a greater percentage change in price over the previous year?   product b recorded a greater percentage change.  justify your answer: the equation for product b is  y= 10000(.56)^x , and 1 - .44 = .56product b decreases by 44% per year
