Hello fogundiy,

Below is the answer to the problem with an explanation from our senior

Manhattan Review instructor, George:

Answer to Question 42 is (E):

First figure out which are the cheapest roses. The first bunch is $4.30

per rose, the second is $3 per rose, the third is $50/12 per rose. The

third is obviously the cheapest.

Clearly, to purchase the maximum number of roses, almost all of the

roses will have to be of the cheapest sort. How many can you purchase

for $680? Divide 680 by 25/12. That comes to 326.4. Look among the

answer choices. How much will 324 of the cheapest cost? The answer is

$675. Therefore, we have $5 left over. We can buy an additional rose.

There is only one answer that is greater than 324, and that's (E), which

is 325.

We hope this explanation helps! To receive a free online practice exam
