You can put this solution on YOUR website!
Cost function:C=4x+5y
Constraints:
2x-4y<=10
2x+y>=15
x>=0
y>=0

Two vertices:(0,15) and (7,1)
CHeck the value of the cost function and see which vertex minimizes the cost function.
I'll do one, you do the other,
C%280%2C15%29=4%280%29%2B5%2815%29=0%2B75=75
