Hello, What would be the inequalitie for the following problem,

A company can produce up to 10 truckloads per hour of X or up to 5 truckloads per hour of Y.

cheers

X <= 10, Y <= 5.

**Nylex**)X <= 10, Y <= 5.

Hello, Did you mean to say the |X| <= 10. and |Y|<=5 or just as how you have written before.

the company cant produce e.g. -7 goods per truckload, can they? (unless they are producing electric charges or antimatter)

Hello, Is it necessary to include 0 as the company could produce no Loads of X or Y .

but are x and y linked in some way? for example, is 2 lots of x equal to one lot of y? so if they are producing 8 truckloads of x, they can only produce 1 truckload of y?

yes, so the inequalities are 0<=x<=10 0<=y<=5

but are x and y linked in some way? for example, is 2 lots of x equal to one lot of y? so if they are producing 8 truckloads of x, they can only produce 1 truckload of y?

**elpaw**)yes, so the inequalities are 0<=x<=10 0<=y<=5

but are x and y linked in some way? for example, is 2 lots of x equal to one lot of y? so if they are producing 8 truckloads of x, they can only produce 1 truckload of y?

they give you limits ie The trucks available can carry up to 6 loads of X per hour or up to 10 loads per hour of Y .

and so for this phase they require to work out the inequalities again. ( truck capacity measurement)

Final phase, it says no more then 7 loads per hour can be handled at the loading phase of the operation. They want inequalitiy for this as well( loading phase)

and the profit per truckload of X is $40 and per trucload of Y is $60.

**or**, so I think this would be correct.

0< x + 2y <= 10

I'm assuming that x takes half the work to produce than y. You're correct, but you have to make that assumption, because the word or means that two seperate inequalities for x and y won't ever work. x could be 10 and y could be 5 according to the first solution, which is clearly wrong.

I'm assuming there is a linear relationship.

but then or could be strictly or. i e he can only produce x or y, not both at the same time.

**elpaw**)but then or could be strictly or. i e he can only produce x or y, not both at the same time.

1) THe company can produce up to 10 truck loads of X per hour or up to 5 truckloads per hour of Y.

2) The trucks available can carry up to 6 loads of X per hour or up to 10 loads per hour of Y .

and so for this phase they require to work out the inequalities again. ( truck capacity measurement)

3)Final phase, it says no more then 7 loads per hour can be handled at the loading phase of the operation. They want inequalitiy for this as well( loading phase)

I think that the question implies 'AND' in statistical terms ie X AND Y can be produced. t

so therefore would the inequality 0< x + 2y <= 10 be ok for 1st phase.
