Answer:

18

Step-by-step explanation:

(Note: I'm assuming that "starts out with" refers to the count before buying the four boxes)

Let x be the number of boxes Emily starts out with.

(x + 4) / 2 = 11
\frac{x}{2} + \frac{4}{2} = 11
\frac{x}{2} + 2 = 11

We multiply both sides by 2 to eliminate the fraction.

x + 4 = 22

x = 22 - 4

x = 18
