Problem Solving

A certain farmer pays $30 per acre per month to rent farmland. How much does the farmer pay per month to rent a rectangular plot of farmland that is 360 feet by 605 feet?
(3,560 square feet = 1 acre)

A. $5,330
B. $3,360
C. $1,350
D. $360
E. $150

First thing 1 acre =43560
360*605/43560=5
5*30=150

Good Luck

Just a gut feeling about this...

While the scope of this word problem is not outside the world of GMAT questions, the actual calculations for solving it are pretty ugly, which makes me question whether this is an actual GMAC (or the former ETS) question.

I try to use as little long-division as possible, but found myself breaking down those awfully large values just to factor out and cancel integers in the numerator and denominator.

Blegh.

My concern is more about whether we need to remember all these conversion ratios such gallon to ounce, mile to feet etc

from what I've seen, the GMAT questons will provide you with all the needed conversion ratios, like in this problem.
(3,560 square feet = 1 acre)

i believe you should know how to do conversion. although gmat doesn't expect you to remember the specific #'s such as 12 inches in 1 feet, you should be able to convert secs to hours with variables x and y...i had a similar question like that on the real gmat. or they might give you some ratio problem with variables and expect you to do the conversion

How can we find this from 3,560 square feet = 1 acre

First thing 1 acre =43560

Can someone pls tell how you get 1 acre = 43560 sq feet. The stem mentions 1 acre = 3,560 square feet.

Thank you very much Ian.

You saved my head. ..I had been banging it in the past to get to know how to calculate the 1ac from the info given...

I KNOW!!! This is such a straight calculation problem. But the question contained errors which was really cracking me out!!! Bummer!
