Your job is to do ONE of these problems.
Due Wednesday before thanksgiving break!

For both projects...
Every input must be checked for stupidity.  (i.e. no one can plan -10 acres of corn).
Any input that's stupid should turn red.

The background should reflect the state of the input.  If the plane is
going to crash, show a picture of a something appropriate.  If they are
using to much water, show a drought picture.  

The backgrounds should be stored on your laptop, not on the web.

Place all the inputs in one visual box.  The box should be centered left-right
on the screen.

Set the title to something reasonable.

Embed a video of something appropriate (don't show deadly plane crashes).









Planes
-------------------------------
My plane empty weighs 1504 pounds.  It has an arm of 86.7 inches.
Front seat passengers have an arm of 80.5 inches.
Rear seat passenger have an arm of 118 inches.
The plane can carry between 0...300 pounds of fuel. The fuel has an arm of 95 inches.

Ask for the front seet weight.
Ask for the rear seat weight.
Ask for the amount of fuel.
Nothing can be below zero.

Compute the total weight.
Compute the total moment.  The moment of each thing is the weight * arm.
Compute the center of gravity.  That is moment  / weight.
If the center of gravity is inside of 82 ... 93 inches, OK else crash.
If the total weight exceeds 2450, crash.
Bonus:  Draw a weight/balance graph as shown here.  










Farming
-------------------------------
Your job is to ask:
	How many acres should be planted in wheat?
	How many acres should be planted in corn?
	How many acres should be planted in rice?

	Nothing can be less than 0.
	The total cannot exceed 100 acres.
	The total amount of water used cannot exceed 100.  
	Corn uses no water (just rain).
	Each acre of wheat uses 1 waters.
	Each acre of rice uses 10 waters.

Show them a bar chart with two bars:
	a bar that goes from bottom to top as they use the 100 acres.
	a bar that goes from bottom to top as they use the 100 waters.
	The bottom of the bars don't move based on the numbers

Show them the total profit:
	Each acre of corn is worth $100.
	Each acre of wheat is worth $150.
	Each acre of rice is worth $500.
