Ok, the first problem (and I dont have the exact numbers but i just need to know how I would do it) is : If a bathtub drips water at a certain rate then how long will it take for the bath tub to be filled?

The second problem is: If you are given a certain amount of money for a building, and each square foot costs a certain amount. Determine how big a building you can build and then graph it.

Help?
