Penelope has several coins, all nickels and quarters in her piggy bank. The total amount of money that she has is $15.65. If Penelope has 13 more nickels than quarters, how many quarters does she have?
\n" ); document.write( "-------------------
\n" ); document.write( "Quantity Eq:::: n = q + 13
\n" ); document.write( "Value Eq::::::: 5n + 25q = 1565 cents
\n" ); document.write( "----------------------------------------------
\n" ); document.write( "Substitute for n and solve for q:
\n" ); document.write( "5(q+13) + 25q = 1565
\n" ); document.write( "30q + 65 = 1565
\n" ); document.write( "30q = 1500
\n" ); document.write( "q = 50 (# of quarters)
