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

where is the 25 and 5x from?
