A limited-edition poster increases in value each year. After 1 year, the poster is worth $20.70. After 2 years, it is worth $23.
81. Which equation can be used to find the value, y, after x years? (Round money values to the nearest penny.) y = 18(1.15)x y = 18(0.15)x y = 20.7(1.15)x y = 20.7(0.15)x
First we want to find the amount that will be worth 20.7 after one year and 23.81 after two years So I assume that Y =p (1.15)^x Where Y 20.7 P ? X 1 year 20.7=p (1.15)^1 Solve for p P=20.7÷1.15 P=18
