You can put this solution on YOUR website!
n+q = 65 subtract q from both sides:
n = 65-q
:
0.05n+0.25q = 8.65 substitute for n:
0.05(65-q)+0.25q = 8.65
3.25-0.05q+0.25q = 8.65
0.20q = 5.40
q = 27 the pickle jar has 27 quarters and (65-27=38) 38 nickels
----------
Check
27*0.25+38*0.05 = 8.65 Correct.
You do the rest.
