Homework Help: Algebra

Posted by Aria on Friday, April 15, 2011 at 10:49pm.

I was given this problem to solve and no matter what order I multiply the variables I don't get the right answer.

27xy, when x=12.7 and y=100.4
the answer is 34,427.16

I cannot figure out the way to achieve this answer.

I find problems with variable fairly easy, but this one with double variables is very confusing. There is not example in the text to help with this.

27 * 12.7 * 100.4 = 34,427.16

Thank you. I didn't think of multiplying from left to right.
