D for me parallelism...

E -not relevant-

D for me too

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:

Backsolve solution pick 150 --> 150*80%= 120 So, 370-120= 250 that can be combined with 150 = 400 again

Backsolve for me start at C $16 the seats will be reduced 15 --> 85 sold Check 85*16 = 1360, BINGO !!

I also picked B

D&B for me too

Opps, duplicated post, sorry..

got A 1) assume that the distance is 80 - suff 2) no info about the return trip - insuff

I also go for E

I cracked 990 to be 9*10*11 9*10*11 = (n+2)(n+3)(n+4) So, n=7

E for me too IMO, B is wrong

vote for B too

E for me,
