A limited-edition poster increases in value each year with an initial value of $18. After 1 year and an increase of 15% per year, the poster is worth $20.70. Which equation can be used to find the value, y, after x years? (Round money values to the nearest penny.)

Exponential growth by 15% per year gives

y = 18(1.15)^x.

(Checking: for x = 1, y = 18(1.15) = 20.70, rounded to the nearest penny.)
