URGENT! Drawing graph from linear programming
Hi... i hope someone can help me because I'm sure i'm working this out correctly but these two lines should cross!!!! can anyone tell me if I'm going wrong anywhere...
Plotting 0.7c + 0.8t = 56
t = 70
so with C on the y axis i have (0,80) and (70,0)
Plotting 0.4c + 0.5t =60
so with C on the y axis i have (0,150) and (120,0)
as you can see these two lines would not cross on a graph!!! these are definately the right numbers... unless i'm doing something wrong that i can't figure out i can only asume i've been given incorrect numbers!! :confused:
If anyone can shed some light Id be really greatful.. this is driving me nuts, its for some uni c/w due in VERY soon and there are about 25 marks of follw up question regarding feasle regions that i need the correct graph for!
Thank you in advance!
