A killer whale has eaten 75 pounds of fish today. It needs to eat at least 140 pounds of fish each day. STEP 1 :a. A bucket holds 15 pounds of fish. Identify an inequality that represents how many more buckets x of fish the whale needs to eat.

Solve the inequality.

The solution is .

STEP 2: b. Should the whale eat four or five more buckets of fish? Explain.

If you only have a choice of whole buckets, the whale should eat _ more buckets of fish. With _ buckets, the whale would get 135 pounds of fish, which_ enough fish for the day.

Answer for Step 1: The killer whale has to eat AT LEAST 5 buckets of fish.

Step-by-step explanation:

Let x represent the number of additional buckets of fish that the whale needs to eat.

A bucket holds 15 pounds of fish. This means that x buckets will hold 15x pounds of fish

A killer whale has eaten 75 pounds of fish today. If It needs to eat at least 140 pounds of fish each day, then the inequality that represents how many more buckets of fish the whale needs to eat is

15x + 75 ≥ 140

15x ≥ 140 - 75

15x ≥ 65

x ≥ 65/15

x ≥ 4.33

The number of buckets can't be a decimal so,

x ≥ 5
