Find 10% of 3500
10%2F100=x%2F3500

Cross multiply:
3500=10x

Divide both sides by 100
350=x

Subtract that from 3500
3500-350
3150

Value after 1 year=$3150

We can use expression:
Original+Value-%28Original+Value%2A10percent%29 per year-------- working equation
So,
3500-%283500%2A10+percent%29
$3150, value after 1 year
Thank you,
