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. Write and solve an inequality that represents how many more buckets of fish the whale needs to eat.

Answer: the whale needs 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
