# A killer whale has eaten 75 pounds of fish today. It needs to eat at least 140 pounds of fish each day A bucket holds 15 pounds of fish. Identify an inequality that represents how many more buckets z of fish the whale needs to eat?

For now drop the unit of measurement of lb

Total needed - total eaten so far = remainder to eat

quantity in 1 bucket x count of buckets = remainder to eat

divide both sides by 15

Thus we have:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
