We studied quantities that decrease or decay by the same factor repeatedly. Suppose a digital camera worth $400 loses 1/3 of its value each year. What is the value of the camera, in dollars, after t years? What is the value of the camera, in dollars, after 5 years?



Answer :

Answer:

Step-by-step explanation:

Losing 1/3 value means 2/3 value remains

Value(t) = $ 400 * (2/3)^t     where 't' is years

  when t = 5    years  

        value (5) = $ 400 ( 2/3)^5 =  $52.67
