Answer:
FV= $669.11
Step-by-step explanation:
Giving the following information:
Purchase price (PV)= $800
Decrease value (d)= 1.5% per year
Number of periods (n)= 12 years
<u>To calculate the value of the card after 12 years, we need to use the following formula:</u>
FV= PV / (1 + d)^n
FV= 800 / (1.015^12)
FV= $669.11

This problem, as written, requires a bit of guessing regarding your intentions. My interpretation is that you want to do this division:
2
----------
1 6/7
If that's correct, here's what to do: rewrite 1 6/7 as 13/7 (an improper fraction).
Then divide:
2
-------- This is equivalent to the multiplication (2/1)(7/13) = 14/13 (answer)
13/7
