Given the information in the prompt, we can go about calculating Lloyd's pay with the following equation: (7.5)($4.50) + 3(1.5)($4.50) However, you can 'rearrange' the math a bit and do it this way instead: 7.5 hours + 3(1.5 hours) = 7.5 + 4.5 = 12 hours (12 hours)($4.50)

You'll likely find the second calculation to be considerably faster than the first. With either approach, you'll still end up with the correct answer, but this goes to show that just because you can answer a question correctly doesn't mean that there might still be a way to improve on what you're doing.

Sorry but i'm new to the site. Why do you post the level of the question for some questions and not the others?

Some posters choose to include this information while others do not. 1) You mentioned how you were new to this website, but how long have you been studying for the GMAT?

Hi hffballer,

With a class-start in April, it sounds like you're relatively early-on in your studies. You'll find that this Forum is a fantastic place to post questions, receive advice and take advantage of the broad knowledge-base available.

1) When are you planning to take the GMAT?
2) What is your goal score?

GMAT assassins aren't born, they're made,
Rich

Daily working hour*Regular Rate + Overtime*Increased Rate
7.5*4.5+ 3*4.5*1.5
Will end in .00 so only D and E left.
7*4+3*4*1=40, answer is slightly more that 40 hence 54 , Choice D

We can create the following expression to determine what Lloyd is paid:

7.5 x 4.5 + 1.5 x 4.5 x (10.5 - 7.5)

33.75 + 6.75(3) = 33.75 + 20.25 = 54
