Are you looking for a solution to this question or are you posting it just for the benefit of others? I ask because the question seems way to easy and I cannot imagine someone having issues solving this. Of course I could be wrong.

This is why I was skeptical about registering to one of these websites because I didn't want to deal with someone underhandedly calling me stupid. I am really struggling with this question. I tend to read too much into a question and it takes me longer to get it, but eventually I get it. I am sorry that everyone is not as swift as you in getting the "easy" problems...

Definitely was not my intention to call you anything. I have been through this phase already and yeah such problems may now seem easy to me. I can assure you definitely was not the case when I started out. Registering to such websites is the best way to learn cause there are lots of people out there who can help you with every problem that you have and you will be doing yourself a dis-service by not posting your problems out here. And besides this is just the first step. There is still a long way to go, but the journey is fun. Keep posting. Would love to continue helping you out.

40 oranges for $5, which makes each orange cost $0.125 (5/40).

Then the store sold each orange for $0.2, so the profits for each orange is 0.2-0.125 = $0.075.

Because there are 40 oranges, 40 X 0.075 = $3

Answer A


this solution is valid, but involves a lot of unnecessary work.

the problem is stated in terms of profit PER CRATE.
since the price of the crate is already given PER CRATE (IE $5/crate), you don't have to find the price per orange. notice that you just wind up taking this quantity and multiplying it back out by 40 again in the next step (undoing what you just did).

instead:
BUY at $5/crate
SELL at $0.20 times 40 = $8/crate
subtract = $3 profit

done.

to the original poster:
just get TAKEAWAYS from the problem. perhaps you didn't know what "gross profit" meant, or didn't know what to do with "per X" or "per Y".

whatever weakness caused you to miss this problem, just make sure that you rectify it.
