Does someone can help?
I don't understand why we have to multiple x by 3 for the first quarter. I thought it would have been an addition instead. So that we would have 3+x for the first quarter. At the 9th quarter we would have had 9x instead of 3x to the 9th power.
Thanks.

Hi didieravoaka,
We're told that every quartercentury (meaning every 25 years), the price of a bushel is X TIMES (meaning multiplication) more expensive. From 1775 to 2000, we have nine 25year 'periods' in which the bushel becomes X TIMES more expensive with each period, so we're clearly talking about a LOT of multiplication. However, the price in 1775 is $3 and the price in 2000 is only $9, so all of that multiplication leads to a total product that is only 3 times more expensive over the course of 9 periods. There's only one answer that has a 3 AND accounts for 9 'periods'...
Final Answer: E
