Question: User: 3 ladybugs equal 90. What does a ladybug with a ladybug subscript equal?
1. **State the problem:** We are given that 3 ladybugs equal 90, and we need to find the value of a ladybug with a ladybug subscript (which we interpret as a single ladybug).
2. **Set up the equation:** Let $L$ represent the value of one ladybug. The problem states:
$$3L = 90$$
3. **Solve for $L$:** Divide both sides of the equation by 3 to isolate $L$:
$$\frac{3L}{\cancel{3}} = \frac{90}{\cancel{3}}$$
which simplifies to:
$$L = 30$$
4. **Interpretation:** The value of one ladybug, or a ladybug with a ladybug subscript, is $30$.
**Final answer:** $30$
