You can put this solution on YOUR website!
(a) & (i)
y%3C=x, directly translated from that condition described.

(ii)
Attempting cost relationship
Highest cost allowed is 4500 dollars.
150x%2B300y%3C=4500
Reducible to
x%2B2y%3C=30
Again, reworded, the cost of the guitars and violins must be less than or equal to 4500 dollars.

You did not say if you want to combine these inequalities for a solution. This can be done easily enough checking on a graph. Plot both equations (the two unique ones; not the unreduced cost one) as their lines, and then test any point in each of the four regions;
What I mean to say is, graph the system:
highlight%28x%3C=y%29 and highlight%28x%2B2y%3C=30%29 onto the same coordinate system. The reason that you want to use the REDUCED cost inequality is because it is easier to use.
