You can put this solution on YOUR website!
either you don't know your own email address or you mis-spelled it or it's a phony. I don't care, here's your answer:
\n" ); document.write( "p + n + q = 151
\n" ); document.write( "and:
\n" ); document.write( "n+1 = q
\n" ); document.write( "3n = p
\n" ); document.write( "0.01p + 0.05n + 0.25q = 10.15
\n" ); document.write( "now substitute for pennies and quarters:
\n" ); document.write( "0.01(3n) + 0.05n + 0.25(n+1) = 10.15
\n" ); document.write( "0.03n + 0.05n + 0.25n + 0.25 = 10.15
\n" ); document.write( "0.33n = 9.90
\n" ); document.write( "n = 30 Sandra has 30 nickels
\n" ); document.write( "Quarters = n+1 = 30 + 1 = 31
\n" ); document.write( "Pennies = 3n = 30(3) = 90
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "Check:
\n" ); document.write( "30(0.05) + 31(0.25) + 90(0.01) = 10.15 Correct
\n" ); document.write( ":
