Question

A computer sells for $900, and loses %30, percent of its value per year.
Write a function that gives the computer's value, V(t) t ( years after it is sold.

Answer 1

Answer:

900(0.7) is the answer of this question

Answer 2

Answer:

V(t) = 900(0.7)^t

Step-by-step explanation:

Losing value at a rate of 30%, percent per year means the computer keeps 100% - 30% = 70% of its value each year.

So each year, the value is multiplied by 70%, percent, which is the same as a factor of 0.7

If we start with the initial value, $900, and keep multiplying by 0.7, this function gives us the value of the computer t years from now:

V(t) = 900(0.7)^t
