Let n = number of nickles
\n" ); document.write( "Let q = number of quarters
\n" ); document.write( "To avoid decimals, work in cents not dollars.
\n" ); document.write( "The problem statement provides us we two equations:
\n" ); document.write( "(1) n + q = 36 and
\n" ); document.write( "(2) 5*n + 25*q = 460
\n" ); document.write( "To solve put n of (1) into (2) or
\n" ); document.write( "(3) 5*(36 - q) + 25*q = 460 or
\n" ); document.write( "(4) 180 - 5*q + 25*q = 460 or
\n" ); document.write( "(5) 20*q = 280 or
\n" ); document.write( "(6) q = 14 and from (1) we get
\n" ); document.write( "(7) n = 22
\n" ); document.write( "Are these correct? Check using (2).
\n" ); document.write( "Is (5*22 + 25*14 = 460)?
\n" ); document.write( "Is (110 + 350 = 460)?
\n" ); document.write( "Is (460 = 460)? Yes
\n" ); document.write( "Answer: Karla has 22 nickles and 14 quarters. \n" ); document.write( "
\n" );
