If she has n nickels and 25 coins in total, that means she has 25 - n dimes. Each nickel is worth 5 cents, obviously, and each dime is worth 10 cents. So the total value would be:
5 * n + 10 * (25 - n) =
5n + 250 - 10n =
250 - 5n

Ann has n nickles worth 5 cents each and 25-n dimes worth
10 cents each.
Total Cents = 5n + 10*(25-n)
= 5n + 250 - 10n
= 250 - 5n
= 5*(50-n)
Any of the above expressions should work

5n + 10 (25-n) = total value.
5 cents for every nickel, plus 10 cents for every dime (of which there are 25 - n).
This can be simplified to:
250 - 5n = total value.

I trust American guy. Painters do no longer come decrease priced. Scraping the popcorn ceiling is an entire different job. it truly is totally time eating to color trim. Bookshelves might take better training and a diverse style of paint than the flat that he might use for the wall.

5*n+10*d
Each nickle (n) is worth 5 cents, and each dime (d) is worth 10 cents.

T=(n+2n)
T=cents
n=125 cents
2n =250 cents
Not sure if this is what you wanted, but it works.
