Hi All,

We're told that the employees of Smith Enterprises received wage increases ranging from 30 cents to 87.5 cents per hour. We're asked for the MAXIMUM wage increase for a 40-hour week. This question comes down to some basic arithmetic (but you might find it faster to do your math in a couple of smaller steps instead of one big step).

Since the largest wage increase is 87.5 cents/hour, we have to multiply that by 40 hours to find the maximum wage increase for a 40-hour week. Depending on how you choose to multiply those numbers, you could start by 'multiplying out' that decimal by multiplying by 2 and then multiplying that result by 20...

(87.5)(2) = 175 cents

(175)(20) = 3500 cents = $35.00

Final Answer: D

It's clear that the maximum wage increase for a 40-hour week would be $40*(87.5/100) = $4*(7/8) = $35.

The correct answer: D

Hope this helps!

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
