A produce company sells crates filled with a mixture of apples (x) and oranges (y) during the holiday season to grocery stores. Each crate contains a total of 72 pieces of fruit. Suppose that a crate has 8 more apples than oranges. Which system of linear equations can be used to determine the number of pieces of each kind of fruit in the crate?
A) x + y = 72
8x − y = 8
B) x + y = 72
x − y = 8
C) xy = 72
x − y = 8
D) x + y = 72
x + y = 8
