Mike has 7 more nickles than quarters. In all he has $1.25. How man nickles does he have?
\n" ); document.write( "Let the number of quarters be: x
\n" ); document.write( "Then the amount of money in quarters: .25x
\n" ); document.write( "Then the number of nickels are: x+7
\n" ); document.write( "and the amount of money in nickels is: .05(x+7)
\n" ); document.write( "The total money is: 1.25
\n" ); document.write( "Problem to solve is:
\n" ); document.write( ".25x+.05(x+7)=1.25
\n" ); document.write( ".25x+.05x+.35=1.25
\n" ); document.write( ".30x+.35=1.25
\n" ); document.write( ".30x+.35-.35=1.25-.35
\n" ); document.write( ".30x=.90
\n" ); document.write( ".30x/.30=.90/.30
\n" ); document.write( "x=3 <--that's the number of quarters
\n" ); document.write( "The number of nickels: x+7=3+7=10
\n" ); document.write( "Sanity Check:
\n" ); document.write( "If you have 3 quarters and 10 nickels, do you have $1.25?
\n" ); document.write( "3(.25)+10(.05)=1.25
\n" ); document.write( ".75+.50=1.25
\n" ); document.write( "1.25=1.25 Yes!
\n" ); document.write( "Happy Calculating!!! \n" ); document.write( "
