oh you bet...i need a little time off but am planning to take it again in early fall so i don't lose too much momentum. it's 700+ or bust! i think 90 points will be pretty reasonable to make up.

i'll be back on this forum full-time soon enough.

oh wow. that's pretty clear--thanks!

For #26... Isn't 1) sufficient? We know that Martin takes the tens digit of the amount of his bill x2 as the amount of his tip. Assuming his bill is $16, he would then leave a $2 tip. 15% of 16 if $1.80, so yes, the tip is greater than 15% of the amount of the bill. A 15% tip on a $49 bill would be ...

The OA for #16 is B. (obviously) not sure how to approach this one...i randomly assigned 10, 20, 30, 40, and 50 as the five positive temperatures. average is 30, sum of largest 3 is 120. B suffices. but then if you put in, say 20, 25, 30, 35 and 50...none of the choices suffice. clearly this isn't t...

thanks Neo. oftentimes i forget to work "backwards" from the answer choices. would have saved me a lot more time!

PS prep

Have been doing speed drills all morning...now having a major brain freeze. Can anyone point me in the right direction on these? thx! 14. Mr. Kramer, the losing candidate in a two-candidate election, received 942,568 votes, which was exactly 40 percent of all the votes cast. Approximately what perce...

Ok, so from I) we know that x<y, thus clearly not sufficient. II) we know that z<0, so the denominator is negative, and for the statement to be true, the numerator (x+y) must be negative as well. But, we can't determine if x is pos or neg. II) alone is not sufficient. Both statements put together, z...

Is the answer B (7.2)? Total distance/total time: (d)/(T1+T2) Let X equal the distance between Milbura and Renmark. Boat travels this distance twice, hence X+X or d. Let T equal the time it takes to travel between each town. Since rate x time = distance, we have 6 x T1=X and 9 x T2=X. So plugging in...
