I propsed myself a problem but i'm having some trouble solving it. I've narrowed it down to this but i need some help on this final part: I have this 2 inequations that must be obeyed: (17/15)x + y > 50000 (1) (2/25)x + (3/10)y > 5000 (2) and I want to find values for x and y that respect those 2 conditions and so that (x+y) is as low as possible. I don't even know if there is a single value of x+y or multiple ones. Is the solution the intersection between the equations (1) and (2)? Plz, tell me how to do this. PS: I'm in high school so try to keep it simple.
