Final answer:
The result of (BI in units) + (# of units purchased) - (# of units sold) is 12 units.
Step-by-step explanation:
The result of (BI in units) + (# of units purchased) - (# of units sold) is 12 units. The result of (BI in units) + (# of units purchased) - (# of units sold) can be understood by simplifying the expression:
(BI in units) + (# of units purchased) - (# of units sold)
Let's say the BI in units is 10, the number of units purchased is 5, and the number of units sold is 3.
Then, the expression becomes:
10 + 5 - 3 = 12
Therefore, the result is 12 units.
