Answer: 
Step-by-step explanation:
Given
There is 
of ham available which costs
cost
i.e.
and we know
So, 
thus 
y = x^2 - 2x - 3
Factored Form: y = (x - 3)(x + 1)
X-Intercepts: (3, 0) and (-1, 0)
Axis of Symmetry: x = 1
Vertex: (1, -4)
Domain: All Real Numbers (or negative infinity to infinity)
Range: y > -4
Hope this helps!
Largest 4 digit number =9999
Smallest 3 digit number= 100
So the product of 9999 x 100 = 999,900
Think of this situation as a system of equations.
let y be the price of hotdogs
let x be the price of hamburgers
5y + 2x = 8
2y + 5x = 9.50
now use your solution method of choice
substitution, elimination, matrices, etc
