[Question]: In a day, Sam hunts 6 animals. Rob hunts half as many animals as Sam. Mark hunts 1/3 of the total of what Rob and Sam hunt. If Peter hunts 3 times as many animals as Mark does, how many animals do they all hunt in a day?
[Answer]: Rob hunts 1 / 2 * 6 animals / day = 3 animals / day. Rob and Sam hunt 3 animals / day + 6 animals / day = 9 animals / day. Mark hunts 1 / 3 * 9 animals / day = 3 animals in a day. Peter hunts 3 * 3 animals / day = 9 animals in a day. The total they all hunt in a day is 6 animals / day + 3 animals / day + 3 animals / day + 9 animals / day = 21 animals.
So the answer is 21.

[Question]: After geometry class, Bill wants to count how many lines he drew. For each shape, he drew one line per side. If he drew 12 triangles, 8 squares, and 4 pentagons, how many lines did he draw?
[Answer]: For the triangles, he drew 36 lines because 12 times 3 equals 36. For the squares, he drew 32 lines because 8 times 4 equals 32. For the pentagons, he drew 20 lines because 4 times 5 equals 20. He drew 88 lines in total because 36 plus 32 plus 20 equals 88.
So the answer is 88.

[Question]: While buying DVDs at the store, Maria received a 25% discount. If the discount she received is $40, how much did she pay in total?
[Answer]:
Since 100 percent represent the original price, and she received a 25% discount which is $40, the original price is 100 / 25 * 40 = 160. Maria paid $160 - $40 = $120 after receiving the twenty - five percent discount.
So the answer is 120.
