Fraction word problem

[hatemath]

Hello all,

I'm stuck on a word fraction problem and would appreciate any help. The word problem is as follows:

Lydia is making a bridal dress from a pattern that calls for 3 1/3 yards of fabric for the skirt, 1 5/6 yards for the bodice, and 4 3/4 yard for the train. Just to be sure she has enough fabric, she wants an additional yard to be added to her order.

If the fabric is priced at $36 per yard, what is the total cost?

My answer: I figured out part of the answer is, $360 11/12, but the answer on the book says it's actually "$36 (11/12) = $360 + 33 = $393".

I'm not sure were the 33 came from. Please help.

Thank you

Total fabric needed = 10/3 + 11/6 + 19/4 +1 = 40/12 + 22/12 + 57/12 +12/12 = 131/12 = 10 + 11/12 yds

Price = 36 * (10 + 11/12) = 36 * 10 + 36 * 11/12 = 360 + 33 = $ 393

By the way, heed Denis's advice and change your "moniker". Around here, we do not like people who hates math.

I'm not sure [where] the 33 came from.

Hi hatemath:

The book has a typographical error. The number highlighted in red above ought to be 10 11/12.

Cheers

I think the line was not "quoted" fully. I believe the line in the book is:


"$36 (10) + $36 (11/12) = $360 + 33 = $393".

"$36 (10) + $36 (11/12) = $360 + 33 = $393".

Dollars are being added to dollars to get dollars:


\(\displaystyle \$36(10) \ + \ \$36(11/12) \ = \ \$360 \ + \ \$33 \ = \ \$393\)
