# Exponential Decay (% decrease/depreciation) $A_t=A_0(1-i)^n$

1. 1
Use the equation $A_{t}=A_{0}(1-i)^n$ to solve.  A car loses 10% of its value every year. If you purchased the car for $25,000, how much is it worth after 7 years? 2. 2 Use the equation$A_{t}=A_{0}(1-i)^n$to solve.  An investment loses 5% of its value every year. If you purchased the investment for$2000, how much is it worth after 5 years?
3. 3
Use the equation $A_{t}=A_{0}(1-i)^n$ to solve.  A computer loses 20% of its value every year. If you purchased the computer for $1700, how much is it worth after 4 years? 4. 4 Use the equation$A_{t}=A_{0}(1-i)^n$to solve.  A camera is purchased for 1400 dollars. If it is worth$800 after 6 years, what was rate of depreciation?
5. 5
Use the equation $A_{t}=A_{0}(1-i)^n$ to solve.  A chair is purchased for 550 dollars. If it is worth $100 after 4 years, what was rate of depreciation? 6. 6 Use the equation$A_{t}=A_{0}(1-i)^n$to solve.  Office equipment is purchased for 6000 dollars. If it is worth$2300 after 9 years, what was rate of depreciation?
