To find the maximum number of tacos that can be ordered with a budget of $100, we first need to determine the cost of each taco.

The sequence provided shows:

- 1 taco costs $3.75
- 2 tacos cost $7.5
- 3 tacos cost $11.25
- 4 tacos cost $15
- 5 tacos cost $18.75

This indicates that the cost of tacos increases by $3.75 for each additional taco. Therefore, the cost for \( n \) tacos can be represented by the formula:

\[
\text{Cost} = 3.75n
\]

We need to find the maximum \( n \) (number of tacos) such that:

\[
3.75n \leq 100
\]

To isolate \( n \), we divide both sides by 3.75:

\[
n \leq \frac{100}{3.75}
\]

Calculating the right side:

\[
n \leq \frac{100}{3.75} = 26.6667
\]

Since \( n \) represents the number of tacos, it must be a whole number. Therefore, we take the greatest whole number less than or equal to 26.6667, which is 26.

Thus, the maximum number of tacos that can be ordered for $100 is:

**26 tacos**
