Question

Muriel purchases a new car for $25,000. The car's value can be modeled by the following exponential function: y = 25000(0.84)^t where y represents the car's value and t represents time in years. What is the decay rate expressed as a percentage?

Answer 1

16%

Explanation:

if you do 1-0.84 it equals .16 & .16 as a percentage is 16% so it is decaying at a rate of 16%
