Given the Following Linear Programming Problem with Two Non-Negative Variables $\left(X_{1}\right.$

Given the following linear programming problem with two non-negative variables $\left(X_{1}\right.$ and $\left.X_{2}\right)$ , find the range of feasibility for the RHS of constraint 1 (hint: both constraints are not binding)
Max: $10 X_{1}+200 X_{2}$
Constraints: $2 X_{1}+5 X_{2} \leq 100 \quad 15 X_{1}+3 X_{2} \leq 90$
Variables are non-negative

A) $\left[150,{ }^{\infty}\right]$
B) $[-\infty, 150]$
C) $[0, \infty]$
D) $[0,150]$
