A=A0(1+i)^n

## The Attempt at a Solution

C=.90+.025*10(.90)
= 1.125.

This answer doesn't take into account that the 2.5% increase is on the previous year's price. Use the equation you considered to be relevant to find the cost of a liter of gas in the 12 years from 2009 to 2021.

Then calculate the cost of a 60 L tank of gas.

so what would A0 be?
