Why do you think this answer is the correct, please put forth effort :D

campbell_st · Answer

remember, you are being asked to compare it to the 1992 price... not yesterday's price

campbell_st · Answer

change  = 2.16 - 1.19

initial price = 1.19

$$Change = \frac{change}{initial~price} \times 100$$
