Q: Ivan buys 48 apples to make 24 full-size pies. He ends up not using as many as he thought because he decides to make mini pies instead of full-size ones, which only use 1/2 an apple each. If Ivan bakes 24 mini pies, how many apples does he have leftover?
A: Ivan wants to bake 24 pies which use 1 / 2 an apple each, 24 pies x 1 / 2 apple each = 12 apples. Ivan uses 12 of his 48 apples, 48 - 12 = 36 apples. Ivan has 36 apples leftover. The answer is 36.

[Question]Aliens and Martians have different numbers of limbs. Aliens have three arms and eight legs, while Martians have half as many legs and twice as many arms. How many more limbs will five aliens have than five Martians?
