Answer:
The value of the computer is given by 900(0.7)^t.
Step-by-step explanation:
A computer sells for $900.
If the price of the computer loses 30% of its value per year, then it is compounded every year.
Now, the price of the computer t years after it is sold will be
900(1 - 30/100)^t = 900(0.7)^t ........... (1)
Therefore, the value of the computer is given by the above equation (1). (Answer)
