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
