I simply solved the problem using different numbers until it worked. You start by multiplying 7 and .40 together to get the total for the books. Then, you multiply 27 by 0.05 to get the total for the pamphlets. The total equals $4.15 so you know you have the right answer. I hope this helped. Good luck and best wishes. \n" ); document.write( " |
