Thread: The price of Apples SAT

1. The price of Apples SAT

I know this is a basic question, But i really don't under stand how to get the cents ,....

2. It should be clear that if 1lb is 6 apples, then 2lbs is 12 apples...

10lbs : $d 1lb :$d/10

2lb : $d/5 = d/5 x 100c = 20d c. 3. Originally Posted by Prove It It should be clear that if 1lb is 6 apples, then 2lbs is 12 apples... 10lbs :$d

1lb : $d/10 2lb :$d/5 = d/5 x 100c = 20d c.
I already know the dozens is 12 which is 1 pound but after that i get stuck. Like i know the answer must be cents but idk how can i find out 2lbs out of 10lbs

4. The answer should be A.
See if 1 pound is 6 apples.
2 pound is 12 apples.
Knowing that 10 pound equals to d.
To get 2 pounds, we need to divide d by 5= d/5.
After this, we know that d is in dollars not in cents.
So we multiply d/5 by 100.
We should get 20d.

I don't know how are you getting the 5=d/5 are you just doing 10/2?

6. Hm... let me try this:

10 lbs <=> 60 apples <=> $d (where <=> means equivalent. Since 1 lbs <=> 6 apples, 10 lbs <=> 60 apples) You want 12 apples, so divide everywhere by 5 to get: 2 lbs <=> 12 apples <=>$ d/5

Then, just convert this into cents by multiplying by 100.

I get right that 60/12 = 5 and then d/5 x 100 = 500 .... that is what i get

8. No i didn't mean that.
What i meant was DIVIDE D BY 5 WHICH EQUALS TO D/5

9. d/5 x100 is not equals to 500.
it's 100d/5.
When divided, you get 20d.

No. You want to get 12 and to do so, you divide by 5 everywhere.

10 lbs <=> 60 apples <=> $d Divide by 5: 10/5 lbs <=> 60/5 apples <=>$ d/5

2 lbs <=> 12 apples <=> \$ d/5

11. At this stage you should do this problem by the technique of picking numbers.

Let's choose a value for d, how about d=10, so that 10 pounds of apples is 10 dollars. Thus the apples cost 1 dollar per pound. So it's 1 dollar for 6 apples, and therefore 2 dollars for 12 apples. 2 dollars is equal to 200 cents. Put a nice big circle around the number 200. That's the answer you want to get.

Now, since we chose d=10, we substitute 10 in for d in each answer choice and use our calculator. We get the following:

(A) 200
(B) approximately 166.67
(C) 50
(D) approximately 16.67
(E) .5

Since (A) is the only answer that came out to 200, the answer is choice (A).

Important Remark: The answer is not (A) because (A) came out correct. The answer is (A) because the other 4 choices did not come out correct. You must try all 5 choices before selecting your answer.

Thanks now i feel I had a better response there
