Question

Write an inequality for this situation; Kristen has a goal to walk at least 20 miles each week

x ≥ 20
x ≤ 20
x 20

Answer 1

It would be the first one.

Explanation:

When it says "at least" that means Kristen has to walk 20 miles at minimum, but she can walk more if she chooses to. Therefore in context of the problem, the greater than or equal to sign would work best.
