I cannot answer "how much are 30" because it's incomplete. To give you a meaningful answer, I need to know what you're asking the price of. Are you asking:
- How much are 30 apples? The price depends on the store and the type of apple.
- How much are 30 shares of a particular stock? The price fluctuates constantly and depends on the market.
- How much are 30 minutes of a service? The cost depends on the service (e.g., a consultation, a parking spot).
- How much are 30 of a specific item? Please specify the item.
Please clarify your question with the item you're inquiring about. Then I can provide a more accurate response.
