Interpreting LINDO Output in Linear Optimization

Based on the attached file, please anwer:

a. Give the complete optimal solution
b. What constraints are binding?
c. What is the dual price for the second constraint?
d. Over what range can the objective function coefficient X2 vary before a new solution point becomes optimal?
e. What would happen if the first constraint's right-hand-side increased by 700 and the second's by 350?

The attached file (.JPG) format is a study question that is used as a "Do it on your own" type of exercise. I'm learning how to use the LINDO software right now.

The answers I came up with were as follows:
a. 25(140)+30(0)+15(80)=3500+0+1200=4700
b. not sure-- how can I tell?
c. 2.333333
d. Can increase by 10 or decrease by any amount.
e. Same solution would apply since the allowable increase for X1 is 2800 and for X2 is 1199.999878 before a new solution is required.
