given:

If Bob produces
Number of items <= 36 , x dollar per item
Number of items > 36, 3/2 (x) dollar per item.

The week total paid can be calculated as :
If N < = 36 total paid = N*x
If N > 36 total pad = 36x + (N-36)*3/2(x)


stmt 1:

last week paid total = 480.
Clearly we cannot calculate, we do not about N and x.
insufficient.

Stmt 2:

This week paid total = 510
Total no of item last week = N. total no of items this week = N+2.
We do not know the Value of N and x. Insufficient.

Combining both
last week paid total = 480 no of items = N
This week paid total = 510 no of items = N+2
pay for two items = 30
pay for one item = 15.

Still we do not whether 15 is X or 3/2 X as we have no idea about N.
