Yeah you got it. Guess that was too easy!

[TheGoldenGriffin]

A have only $5 bills. A cookie costs $3. You want a cookie but you don't want change. What can you do?

[joelduque]

Buy 5 cookies for $15. Give away 4 pcs. You now have a cookie left.

[TheQwertiest]

you can buy 5pcs which is $15 so you wont get change. or you can just tell them to keep the change

I decided that a $3 cookie is not worth it and keep all my money.

Okay here's a tougher one:

You have 300 rocks you want to transport from one place to another that is 100 miles away. You have a truck that can only hold 100 rocks, but also has a hole so you lose 1 rock for every mile you drive. What is the largest amount of rocks you can take to the destination and how?

(Assume that the lost rock falls out at the beginning of each mile, i.e., you can't move a rock 0.5 miles, and then move it again 0.5 miles)

Assuming you can't pick up the rocks you lost?

So if your drive 2 mph you lose 2 rocks per hour and if you can go 400 mps you will lose 400 rocks every second?
