Question

An electric can opener is worth 36 dollars when it is new. After each year, it is worth half what it was the previous year. What will it's worth be after 8 years? Round your answer to the nearest cent. Write the model.

Answer 1

So the equation is f(x)=36*(.5)^8, since your principal worth is 36 and it depreciates by 1/2 each year, which is 14 cents.
