In America any boy may become President and I suppose it's just one of the risks he takes, but the thing that impresses me the most is the way parents obey their children.

Oh so very close, good try.

Naturally I am very happy for you; but who the heck is Lucy?
I am a pig but where did I go wrong?
Mark comes to the rescue, "
you concatenated the numbers instead of multiplying them"
Keep it quiet will ya, I would rather be thought stupid than have you prove it!
Mark:
CHANGE FOR A DOLLAR
You can keep two of the pennies in your pocket. The answer is the coefficient of x^100 in the following product:
(1+x^5) *
(1 + x^5 + x^10 + x^15 + x^20 + x^25) *
(1 + x^10 + x^20 + x^30 + x^40 + x^50 + x^60 + x^70 + x^80) *
(1 + x^25 + x^50 + x^75)
If that makes 21, rock on! :wink:
HOLE
A cube with double the dimensions has eight times the volume.
(That is very true. However, in this case it is 1/8 the size of the large hole)
Therefore, it will take 64 days.
(I think you multiplied the numbers instead of concatenated them)
Rap:
Lizzie and the dollars---3+3*6=21
Farmer and the Hole---Farmer can move 64ft^3 per day and 4^3=64 ft^3----1 day
Thank you Rap for your accurate and timely intervention.
