He has 4 more quarters than dimes:
q=d%2B4
and 3 more dimes than nickels:
d=n%2B3
If n represents the number of nickels he has, then he has %28n%2B3%29 dimes, and %28%28n%2B3%29%2B4%29=%28n%2B7%29quarters.
The total value of all his coins is:
5%2An%2B10%2A%28n%2B3%29%2B25%2A%28n%2B7%29=5n%2B10n%2B30%2B25n%2B175=40n%2B205
Answer: A. 40n%2B205
