My hand writing is horrendous so I am going to retype the answers I got here:

x=# of cookies-plain
y=# of Iced cookies


f(x,y)=1.5x+2y
x>0
y>0
.1x+.15<15
x+y<140
x+.7<110 which equals x<109.3
.4y<32 which equals y<80


(x,y) 1.5x+2y f(x,y)

(0,0) 1.5(0)+2(0) 0
(30,80) 1.5(30)+2(80) 205
(109.3,407/15) 1.5(109.3)+2(407/15) 13093/60
109.3,0) 1.5(109.3)+2(0) 163.95


Here is the link to the graph I needed to make to find the above information: http://img212.imageshack.us/img212/1553/graphlj8.jpg
