You can put this solution on YOUR website!
Amount of money remaining would be 200 dollars MINUS n*5 dollars.
This is {n CDS * 5 dollars/CDS}, or putting together the numbers separately from the units, 5n CDS%28dollars%2FCDS%29.

The formula for amount remaining on the gift card is then R%28n%29=200-5n.

The second question only needs let n=10 and compute R(10).
