Sammy bought a pound of butter and divided it up into 50 equal pieces. He gave 7 pieces to Sue, 3 pieces to Bobbie, and 1 piece to his mother. Later in the evening he cut the remaining pieces in half and gave 1/4 of them to Kirby. What was left he threw up in the air and the following happened: he caught 50% in his mouth, 20% in his left hand, and 10% in his right hand, and the remaining ones fell in a perfect stack. He cut the stack in half and tell me, how many pieces were left?

It doesn't work. After giving pieces to Sue, Bobbie, and his mother, Sammy had 39 pieces left. When he cut those in half, he had 78 pieces.

He 1/4 of them to Kirby because 4 does not divide 78.

The problem is no good.

It's a pretty poor story because it falls apart.

If he had fifty pieces originally and he gave 7 to Sue, 3 to Bobbie, and 1 to his mother, then he had 39 pieces left. If he then cut them in half, he would have then had 78 pieces and he *couldn't* have given 1/4 of them to Kirby because 4 doesn't divide 78 exactly.

End of story

All of them were left since you didn’t specify what the recipients did with their butter after they received it. However, if you are trying to ask how many pieces were left after he cut the last stack in half, then:

50-11=39 pieces left after dividing
39x2=78 pieces left that evening
78x(3/4)=58.5 pieces left after Kirby
58.5x20%=11.7 pieces in the perfect stack
11.7x2=23.4 pieces in the cut stack

Logically not possible since any fractional piece is a whole piece, but the math is there.

50 Pieces - 7 - 3 -1 = 39
cut 39 in half = 78
give 78/4 = 19.5 to kirby leaves 58.5
caught 80% so dropped 20% = 58.5*0.2 = 11.7
cut stack in half = 11.7 * 2 = 23.4

he gave 11 pieces away and he was left with 39 and he gave a 1/4 to Kirby so he was left with 29.25 then he caught 50% of that in his mouth and was left with 16.63 then he caught 20% of that in his right hand and 10% in his left and he cut the rest in 1/2 and so he's left with 2.49 pieces of butter

He would have 24 pieces, but not all of them are uniform in size.

50 pieces - 11 = 39
Cut pieces in half = 78
Gave 1/4 to Kirby = 59 (actually 58.6) pieces(not uniform in size)
Caught 80% of pieces, so 12 (actually 11.8) fell in stack
Cut stack in half = 24 (23.6) (actually not uniform in size)

the vehicle catches up at a value of 40 5 - 30 = 15 miles in protecting with hour. The bus has a 15 minute (a million/4 hour) head commence in which it is going 30 • a million/4 = 7.5 miles (distance = % • time). So the vehicle catches up in 7.5/15 = a million/2 hour, 12:30 PM

after he threw the pieces in the air and caught them he had 7.35 pieces in a perfect stack. IDk what you mean by he cut the stack in half. He would have 3.675 if you were supposed to divide by two at the end.
