The Jaspers collect nickels,dimes,and quarters in a jar. When they count the change in the jar there are twice as many nickels as there are quarters. If there is $15.30 in dimes and $74.80 in all how many quarters are there?

\n" ); document.write( "Quantity Equation: n = 2q\r
\n" ); document.write( "\n" ); document.write( "Value Equation: 5n + 1530 + 25q = 7480 cents\r
\n" ); document.write( "\n" ); document.write( "-----------------------------------
\n" ); document.write( "Substitute to love for \"q\":
\n" ); document.write( "5*2q + 1530 + 25q = 7480
\n" ); document.write( "35q = 5950
\n" ); document.write( "q = 170 (# of quarters)
\n" ); document.write( "-------
\n" ); document.write( "Since n = 2q, n = 340 (# of nickels)
\n" ); document.write( "------------
\n" ); document.write( "Since # of dimes = 1530/10 = 153 (# of dimes)
