First you need to find out how much wheat flour is used in 5 loaves. Can you take the challenge?
OpenStudy (nerdsarecool):
Yes
OpenStudy (nerdsarecool):
So do we need to multiply 3.20 by 5
OpenStudy (nerdsarecool):
16 is fifteen loaves
OpenStudy (anonymous):
No, because that is the combined flour. We are looking for the wheat flour alone.

So, to find the corn flour in 5 loaves, subtract the wheat flour from the total flour.
OpenStudy (nerdsarecool):
0.95

was tax. What was the price of each CD before tax?
OpenStudy (anonymous):
Subtract the tax from your total.

Yes, now because all the CD's were the same price, divide 44.4 by 3

Yup, and I'm 100% sure, Sorry about the first one again.
