question from OG 10th

1) Closing price doubled. Doesn't say anything about price. INSUFF

2) Closing price increased by $4.50. Doesn't say by how much. INSUFF

1+2) Price doubled to 4.50. We can then say that price in 75 was 2.25

The problem states that price doubled from 60 to 75. So, if price was 2.25 in '75 then price must be 1.125 in '60

I think so at least..

Thank you max for your reply.

IF the sentence says price increased "TO" $4.5 instead of increased "by" $4.5, the closing price of 84 is detrmined at $4.5. but if it says increased "by" $4.5, I thought that means it only tells you the increase from 75 to 84 is $4.5 and not actualy closing price.

Dose it make any difference betwen increase to and increase by? (I think it dose, that's why I am stuck...)

thanks!

well there is a difference..... the price increased to 4.5 means that the price may 1 1984 is 4.5 $.... when it says increased by 4.5 $ it means that u add 4.5 $ to the price of may 1 1975.... in either case the answer wuld be C.... the first case has already been explained....

for the second case..... the first statement says that the price is doubled .... the second satement says that the price increased by 4.5 $.... that means that the price on may 1st 1975 was 4.5$ and on may 1st 1984 was .... 4.5 +4.5=9 $..... hope this helps....

gabriel, thanks for your reply:) I think I finally got it..
