A Warehouse for Storing Chairs and Tables Has 950 Square $11 x + 18 y \leq 921$

A warehouse for storing chairs and tables has 950 square feet of floor space. Each chair requires 11 square feet of floor space and each table requires 18 square feet of floor space. Write a linear inequality for this space constraint where x is the number of chairs and y is the number of tables.

A) $11 x + 18 y \leq 921$
B) $18 x + 11 y \leq 950$
C) $11 x + 7 y \leq 921$
D) $11 x + 18 y \leq 950$
E) $11 x + 18 y \geq 950$
