Anyway, they're asking for the value of q. We can set up a system of equations, one for the total # of coins, and another for the total value of the money

total # of coins is 108, so n + q = 108
the total value of the coins is $21. 0.05 * n gives the total value of the nickels, and 0.25 * q gives the total value of the quarters. therefore, 0.05n + 0.25q = 21.

solve for q.
