Origional question: Books cost .40 and pamphlets .05 at the book sale. Mr. Jones spent $4.15 at the book sale and purchased 20 more pamphlets than he did books, how many pamphlets did he buy?

Solution: 7 x 0.40 = 2.80
27 x 0.05 = 1.35
2.80 + 1.35 = 4.15

I used my famous guess and check system to solve this problem. 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.
