2 train-lines leave the same central station at the same time.
line 1: [itex]f(x) = 6000 + 50x[/itex]
line 2: [itex]g(y) = 2000 + 50y[/itex]
x and y are the number of departures pr. hour. line 1 can have 2 departures pr. hour pr. trian, and line 2 can only have 1 departure pr. hour pr. train.
There is a total of 100 trains.
I'm supposed to show this graphically.
I have:
[itex]x + y \geq 100[/itex]
Since line 1 can have 2 departures pr. hour. pr. train, I also have:
[itex]f(x) = 6000 + 50(2)x[/itex]
But, I'm confused on how I show this graphically? What do I need to plot here?
Plotting f(x) and g(y) doesn't make any sense at all.
