Beth bought a 20-ounce bag of flour for $4.40. How much does the flour cost per ounce

4.40/20 = 0.22

Each ounce of flower cost 0.22 cents per ounce.

If 20 ounces for flour cost 4.40

where x is one ounce of flour, then we can write it like this:

20x=4.40

then we need to divide by 4.40 to get to the x:

x=4.40/20=0.22

So the flour costs 22 cents per ounce.

(Let's check: 0.22 times 20 = 4.40. correct!)
