document.write( "Question 362889: Due to melting, an ice sculpture loses one-half its weight every hour. After 8 hours, it weighs 5/16 of a pound. How much did it weigh in the beginning.\r
\n" ); document.write( "\n" ); document.write( "I did 5/16+8 and put the fraction into decimal form then added the two together and got 8.3125. Then its says 1/2 of the that is lost in weight. Now I multiplied the 8.3125 to .05(The decimal of 1/2) then got 4.15625. I dont know if that is correct or what and i used samdep instead of pemdas its pemdas backwards because it says to solve backwards using asmdep.

Let's say it weighed \"W\" to start.
\n" ); document.write( "After \"1\" hour, it weighs \"W%2F2\"
\n" ); document.write( "After \"2\" hours, it weighs \"W%2F4\"
\n" ); document.write( "After \"3\" hours, it weighs \"W%2F8\"
\n" ); document.write( "After \"4\" hours, it weighs \"W%2F16\"
\n" ); document.write( "After \"5\" hours, it weighs \"W%2F32\"
\n" ); document.write( "After \"6\" hours, it weighs \"W%2F64\"
\n" ); document.write( "After \"7\" hours, it weighs \"W%2F128\"
\n" ); document.write( "After \"8\" hours, it weighs \"W%2F256\"
\n" ); document.write( "But you know that
\n" ); document.write( "\"W%2F256=5%2F16\"
\n" ); document.write( "So then,
\n" ); document.write( "\"W=%285%2F16%29%28256%29\"
\n" ); document.write( "\"highlight%28W=80%29\"lbs
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "You could also work it backwards,
\n" ); document.write( "After \"8\" hours it weighs \"5%2F16\"lb.
\n" ); document.write( "After \"7\" hours it weighed \"2%285%2F16%29=5%2F8\"lb.
\n" ); document.write( "After \"6\" hours it weighed \"2%285%2F8%29=5%2F4\"lb.
\n" ); document.write( "After \"5\" hours it weighed \"2%285%2F4%29=5%2F2\"lb.
\n" ); document.write( "After \"4\" hours it weighed \"2%285%2F2%29=5\"lb.
\n" ); document.write( "After \"3\" hours it weighed \"2%285%29=10\"lb.
\n" ); document.write( "After \"2\" hours it weighed \"2%2810%29=20\"lb.
\n" ); document.write( "After \"1\" hours it weighed \"2%2820%29=40\"lb.
\n" ); document.write( "After \"0\" hours it weighed \"2%2840%29=highlight%2880%29\"lb.
\n" ); document.write( "
\n" ); document.write( "
\n" );
