There is an ambiguity in the solution .if y=700,x<=3300 and z<=3000.now we sum up x,y and z .then it doesn't sum to 10700,as opposed to given in the question.please explain

Iam referring to the 1st question i.e..what is the minimum budget spent on at least two channels??

the question is on minimum budget on 2 and 3 channel. to find the minimum of Y, we need to maximize X and Z.! that's why we have maximised X and Z to 5000 and the remaining 700 to Y.!
could you pls tell me how X and Z becomes 3300 and 3000 respectively?
