A lot of similar Q's are out there....   one more time

 

q = quarters             value = 25 q

d=dimes = q+13       value = 10(q+13)        summed = 200

 

25q         + 10(q+13)       = 200

25q         + 10q +130      = 200

35q                                 =70

q = 2 quarters           d = q+13 = 15 dimes
