Let's fill in the blanks step by step:
1. For sandwiches, the total cost will be \(2.5x\), so the expression becomes:
\[
30 - 2.5x
\]
2. For drinks, we already have:
\[
25 - 1.5x
\]
3. For gifts, the total cost will be \(3x\), so we rewrite it as:
\[
25 - 3x
\]
Now, let's combine the expressions:
\[
(30 - 2.5x) + (25 - 1.5x) + (25 - 3x)
\]
This simplifies to:
\[
30 + 25 + 25 - 2.5x - 1.5x - 3x
\]
Combining the constants:
\[
80 - (2.5x + 1.5x + 3x)
\]
Combine the coefficients of \(x\):
\[
80 - (2.5 + 1.5 + 3)x = 80 - 7x
\]
So, we have:
\[
80 - 7x
\]
Now, this represents the amount of money of the $80 she originally budgeted that she would have left over.
If 5 friends, including herself, came to the party, that means \(x = 6\) (because she is included in the count). Now we can substitute \(x = 6\) into the expression:
\[
80 - 7(6) = 80 - 42 = 38
\]
So, if 5 friends, including herself, come to the party, she'd have **$38** remaining.
**Final sentence: So if 5 friends, including herself, came to the party, she'd have $38 remaining.**
