\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "\"Sarah has $3.50 in quarters and nickels.\"
\n" ); document.write( ".05n + .25q = 3.50
\n" ); document.write( ":
\n" ); document.write( "\" She has 2 more quarters than nickels. \"
\n" ); document.write( "q = n + 2, this means we can substitute (n+2) for q, right?
\n" ); document.write( ":
\n" ); document.write( "I need an algebra equation for this.
\n" ); document.write( ":
\n" ); document.write( "Using the first equation, .05n + .25q = 3.50, substitute (n+2) for q, find n
\n" ); document.write( ".05n + .25(n+2) = 3.50
\n" ); document.write( ".05n + .25n + .50 = 3.50
\n" ); document.write( ".30n = 3.50 - .50
\n" ); document.write( ".30n = 3
\n" ); document.write( "n = 3/.3
\n" ); document.write( "n = 10 nickels
\n" ); document.write( ":
\n" ); document.write( "I'll let you find the number of quarters. Check your solutions in the 1st eq \n" ); document.write( "
