**Steve**, Wednesday, December 11, 2013 at 5:18pmLCM(6,14) = 42, so the 42nd guest will receive both.

For the mints, 256 guests at 1/12 lb/guest shows she needs

256/12 = 21.33 lbs of mints

8 1/2 lbs only serves 102 guests (8*12 + 6)

**Sam**, Wednesday, December 11, 2013 at 5:19pmFor the first one:

if you have to, just list em all out

Mugs: 6,12,18,24,30,36,42,48,54,60....

Shirts: 14,28,42,56,70....

See any numbers in common so far? Yep: the 42. So the 42nd guest will get both

Second one: Can't figure it out, cuz not enough information, did you leave something out, like how many place settings there are?

**Sam**, Wednesday, December 11, 2013 at 5:19pmYeah what Steve said

**Someone**, Saturday, December 6, 2014 at 4:55pmYou have to find the LCM=Least Common Multiple.

So if your prime factorize 6 and 14 you will get 3x2 for 6 and 7x2 for 14.

There is a set of 2's so you take one and cross out the other. Now take 3 and 7 since this is LCM we keep the remaining.

7x3x2=42

42th visit
