My intuitive guesses:
1. 2x
2. y

1) Um, x + x?
2) Still y?
These are very intuitiony answers.

Sir, it's not an offence to let your cat eat your bacon. Okay? And we don't arrest cats, I'm very sorry.
is there something depressing about the narcoleptic puppy?
Both narcoleptic puppies fall asleep when they get excited. The second one does it much more often. He gets excited when eating, so the only way he can actually eat a meal is if his owners hold him and constantly stroke him to keep him calm.

Sometimes I trip on how happy we could be.
I think I knew that about Filene's but not the rest. Are they of specific department stores? I mean, I guess Nordstrom Rack's provenance is pretty self-explanatory, and isn't Filene's something easy like that too?
Filene's Basement was sold off from the Filene's Department Store (now Macy's) years ago, but the original one was literally the basement of the main department store, where they put unsold marked-down stuff.

I would have said 1.5x.

the hardest to learn / was the least complicated
1) You are driving a car, and you accelerate from 0 to 25 mph. Say the amount of energy required is x. Now you continue to accelerate from 25 mph to 50 mph. What is the total amount of energy you used to accelerate from 0 to 50 mph?
I want to say it would be more than x, but less than 2x, since you have inertia on your side. Maybe 1.5x?
2) You drop a heavy object from a height of 10 feet, and when it hits the ground it has a velocity of y. What would be the velocity if you drop it from 20 feet? From 40 feet?
Isn't it always y, no matter the height?

I'm gonna wait a bit to see if others chime in, then I'll post the answers.

Don't you need calculus to solve this?
