The Vandelay furniture company makes bookshelves and tables. Consider the following Linear Programming Model: 4 X₁ = the number of bookshelves made in a day. X2 = the number of tables made in a day. Maximize: Z 50X₁ +50X₂ = Profit ($) Subject to: 20X1 + 12.0X2 <= 100 Labor (hours) 7.8X1 + 10X2 <= 50 Lumber (board-feet) What's the lowest that the profit on a bookshelf can be, without changing the optimal solution? Another way to ask this is, what's the lower bound on the sensitivity range for C₁? (Round your answer to 1 decimal place.)

linear programming
The Vandelay furniture company makes bookshelves and tables.
Consider the following Linear Programming Model:
4
X₁ = the number of bookshelves made in a day.
X2 = the number of tables made in a day.
Maximize: Z 50X₁ +50X₂
=
Profit ($)
Subject to:
20X1 + 12.0X2 <= 100
Labor (hours)
7.8X1 + 10X2 <= 50
Lumber (board-feet)
What's the lowest that the profit on a bookshelf can be, without changing the optimal solution?
Another way to ask this is, what's the lower bound on the sensitivity range for C₁?
