Tom has 30 coins with a value of $3.30. If they are all nickels and quarters, how many of each kind of coin does he have?

q = quarters                       value = 25q

n = nickels = 30-q              value = 5(30-q)        summed  they equal 330

 

25q          +     5 (30-q)             = 330        solve fo q the # quarters     then nickels = 30-q
