St -1 == not sufficient. Doesnt say anything about the items or individual item price.

St-2 == not sufficient. Doesnt say anything about the individual item price to construct the equation.

From sts (1) and (2),
510-480 = 30 for 2 items
so for each item $15. Now we don't know if these 2 items are part of 36 items or more than that.
It could be that these 2 items are part of 36 items, so x= 15 and then x1(excess over 36 items) = 22.5
or it could be that these 2 items are over 36 items so x1=15 and x = 10

So answer is E.
