To determine the total number of oranges Julissa gave out, let’s follow the steps below:
1. Identify the number of apartments: According to the problem, there are 6 apartments.
2. Identify the number of oranges given to each apartment: The problem states that Julissa gave each apartment 5 oranges.
3. Calculate the total oranges given out: To determine the total number of oranges, we multiply the number of apartments by the number of oranges given to each apartment. So, we need to perform the following multiplication:
[tex]\[
\text{Total oranges} = \text{Number of apartments} \times \text{Oranges per apartment}
\][/tex]
Substituting the given values:
[tex]\[
\text{Total oranges} = 6 \times 5
\][/tex]
4. Perform the multiplication:
[tex]\[
6 \times 5 = 30
\][/tex]
Therefore, the total number of oranges Julissa gave out is 30.
So, the correct answer is [tex]\( \boxed{30} \)[/tex].
