You can put this solution on YOUR website!
you must convert 4% to a decimal by dividing by 100 or moving the decimal two places to the left. Therefore 4% becomes .04
\n" ); document.write( "Next multiply 80 pounds by .04 and you get 3.2 pounds
\n" ); document.write( " $\"80%2A.04=3.2\"$
\n" ); document.write( "3.2 pounds is the amount of weight being increased so you need to add it to the original 80 pounds
\n" ); document.write( " $\"80+pounds%2B3.2pounds=83.2pounds\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
