A certain species of fish costs $3.19 each. You can spend at most $35. How many of this type of fish can you buy for your aquarium?

Let the number of fish be f. We have the following inequality where "at most" means less than or equal to:
3.19f <= 35

Typing this inequality into our search engine, we get:
f <= 10.917

Since we need a whole number of fish, we can buy a maximum of 10 fish.
