  1. The Duxburys purchased 1375 large bottles at $1.89 per bottle and 690 small bottles $1.38 per bottle. What was the approximate average price paid per bottle? A) $1.63 B) $1.64 C) $1.68 D) $1.72 E) $1.76 Can you guys provide "the shortcut" to tackle this Q Thanks, :tup:
  2. Backsolve solution pick 150 --> 150*80%= 120 So, 370-120= 250 that can be combined with 150 = 400 again
  3. Backsolve for me start at C $16 the seats will be reduced 15 --> 85 sold Check 85*16 = 1360, BINGO !!
  4. Opps, duplicated post, sorry..
  5. got A 1) assume that the distance is 80 - suff 2) no info about the return trip - insuff
  6. I cracked 990 to be 9*10*11 9*10*11 = (n+2)(n+3)(n+4) So, n=7
  7. IMO, A explains why many species were disappeared at the same time
  8. D is correct allow...to is idiomatic, hence C is ruled out have begun for perfect tense
  9. I also go for B, more..than and comparison "at great depths" with "shallow coastal waters"
  10. 2) is clear... sufficient 1) 5-(-5) > 4-(-4)... sufficient D it is
  11. I think using backsolve method should be better for this Q go for D
  12. I solve this Q by means of POE C,D,E can cen be kicked away narrow to A,B B is impossible, hence go for A
  13. my solution T+(T+2) = 18, so T= 8 D1+D2 = 64 = RT+(R+1)(T+2) 64=8R+(R+1)10, R=3 B is the answer...
  14. another vote for B negate B, the conclusion can't be hold
