It's not necessary to change names on this forum. It's obvious that these four questions were posted by one person.

Your last four money questions are the same type

If will do one, then you try the others.

let the number of nickels be x

then the number of quarters is 16-x

5x + 25(16-x) = 220

5x + 400 - 25x = 220

-20x = -180

x = 9

so 9 nickels and 7 quarters

check: 9 nickels and 7 quarters = 16 coins

value: 9x5 = 7x25 = 220

25 = 25 cents = 1 quarter

5 = 5 cents = 1 nickel
