I attempted to try this problem for myself, yet I still got the wrong answer. So can you figure out what I did wrong? I multiplied 0.04 by 2500 and 0.7 by 20. And I still got the wrong answer.\r

For a), you're supposed to ADD .04 times 2,500 TO .7 times 50.
\n" ); document.write( "For b), you're supposed to ADD .04 times 400 TO .7 times 20.
\n" ); document.write( "This should gives you, 135 feet, and 30 feet, respectively.
\n" ); document.write( "What's so DIFFICULT about that? \n" ); document.write( "
