I found that I could have 8 complete pieces of 3/4 yards that I can cut from a length of 6.5 yards. By multiplying 8 by 3/4 yards, this gives me the total length of 8 pieces that I would need to make the bows. This resulting length of 6 yards can then be subtracted from 6.5 yards to yield the portion of the ribbon that will not be used. I hope this makes sense.

I swear 36 is wrong. H cannot be possible for that question. It has to be J. Someone please help me understand what’s wrong with either the test or my thought process

If you want 1 ounce of element X, you need 10 ounces of compound Y because 10$\%$ of compound Y is element X. 16 ounces of compound Y will cost $\$$2.40, so 10 ounces of compound Y will cost 10/16 * $\$$2.40 = $\$$1.50. The premise of the question is that you don’t have to purchase compound Y in whole pound quantities. You can purchase exactly the 10 ounces that you need in order to get 1 ounce of element X.

I can’t find the video answer for Math 24 for form B05. I just paid membership to find this answer explanation and it’s not here.

Dabral says

The video explanation to Question 24 is in the playlist. You just have to scroll backward.

I’m not sure why it formatted so strangely. Sorry about that.

Dabral says

Thanks for answering this. I have fixed the editing because of the math symbols.

Dabral says

One doesn’t have to buy an entire pound, you can purchase any amount similar to buying say flour or sugar.
