Question 3: Exponential Decay A certain computer model is worth $1500

Question 3: Exponential Decay A certain computer model is worth $1500 when it is new and loses 15% of its value each year. The value can modeled by the function V (t) = a b', where V(t) is the dollar value and t is the number of years since the purchase. (a) What is a possible exponential equation for the value? That is, find a and b. (3 marks) (b) What is the value after 3 years? (1 mark) (c) When will the value be 25% of the original value? Round your result to 4 decimal places. (2 marks)
