To answer your 4th question:
\n" ); document.write( "Use the equation is/of = %/100% (This is very informal, of course).
\n" ); document.write( "We don't know what the price of the shoes IS, so we can insert x in place of is. We know the shoes are 55.99, so insert that in place of of. And the 30% goes in place of %, but in decimal form. (0.30). It should look like this:
\n" ); document.write( " $\"is%2F55.99+=+0.30%2F100%25\"$ \r
\n" ); document.write( "\n" ); document.write( "In order to find x, multiply 0.30 by 55.99 and divide by 100.
\n" ); document.write( "Your answer should be 0.16797. Now we add the 2 decimal places that we took away (in the 30%). We should get 16.797. This is the amount of money you save. So add 16.797 to 55.99 and the price of the shoes was 72.79! \n" ); document.write( "
