Fill in the blanks!

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.**
