Greg,
You will need to use simultaneous equations as follows:
Let number of Dimes = D and number of Nickels = N
Then equation 1
10D + 5N = 505
Equation 2
D+N = 63
Multiply Equation 2 by 10 giving equation 3
10D + 10N = 630
Now subtract equation 1 from equation 3 giving equation 4
5N = 125
N = 25 ie 25 Nickels
Now substitute in equation 2
D + 25 = 63
D = 38 ie 38 Dimes
Answer is 38 Dimes and 25 Nickels
