a collection of 35 coins contains nickels and quarters. find the number of nickels given that the total face value of the coins is $2.55.
\n" ); document.write( "---
\n" ); document.write( "Quantity: n + q = 35 coins
\n" ); document.write( "Value:: 5n+ 25q = 255 cents
\n" ); document.write( "--------------------------------
\n" ); document.write( "Divide thru the Value Eq. by 5:
\n" ); document.write( "n + 5q = 51
\n" ); document.write( "n + q = 35
\n" ); document.write( "-------------
\n" ); document.write( "Subtract and solve for \"q\":
\n" ); document.write( "4q = 16
\n" ); document.write( "q = 4 (# of quarters)
\n" ); document.write( "--------
\n" ); document.write( "Since n + q = 35, n = 31 (# of nickels)
\n" ); document.write( "------------------------------------
