You can put this solution on YOUR website!
Let n = no. of nickels
\n" ); document.write( "Let d = no. of dimes
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"Jose has one-third as many nickels as dimes,
\n" ); document.write( "n = $\"1%2F3\"$ d
\n" ); document.write( "we can also write this as, (get rid of those annoying fractions)
\n" ); document.write( "d = 3n
\n" ); document.write( ":
\n" ); document.write( "\"he has a total of 2.45,\"
\n" ); document.write( ".05n + .10d = 2.45
\n" ); document.write( "Replace d with 3n
\n" ); document.write( ".05n + .10(3n) = 2.45
\n" ); document.write( ".05n + .30n = 2.45
\n" ); document.write( ".35n = 2.45
\n" ); document.write( "n = $\"2.45%2F.35\"$
\n" ); document.write( "n = 7 nickels
\n" ); document.write( ":
\n" ); document.write( "You can find the number of dimes, check your solutions in the first equation\r
