Question 1130026

N = number of nickels = number of dimes
Q = number of quarters = 14 - 2N<br>

Using units of cents we can write an equation based on the total VALUE of the coins:
25(14-2N) + 10N + 5N = 175

Solve this to find N=5  then 14-2N = Q = 4<br>

Ans:
 5 nickels
 5 dimes
 4 quarters<br>

Check:
  5*5 + 10*5 + 25*4 = 25 + 50 + 100 = 175
