If a bathtub drips water at a certain rate then how long will it take for the bath tub to be filled?

Name the certain rate of dripping m. Let b be the amount of water in the tub already if needed. x would be the amount of time and y would be the amount of water and add a constraint on y variable since only so much water can be held in the bath tub.

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.

y = mx

m = the price of each square root foot cost

Put a constraint on the y - value. If you 200 dollars than the constraing would be:
