Inequality how to write

Question

Randy started a new job. He was told that he will be able to work at least 20 hours per week. Write an inequality to show how many hours Randy will work each week.

Answer 1

In an inequality, you always have two options----example: A can be larger than B, meaning that it is NOT equal. Or, A can be equal to or larger than B.

Same 2 options when A can be less than B.

The trick here is to read carefully the way the problem is stated: "......work at least 20 hours......". This means that the minimum is 20, but there is no maximum.

So: If H is the hours per week, then H ≥ 20
