Eliza is at least twice as old as her friend's younger sister, Wendy. Which inequality correctly represents Eliza's age, e, compared with Wendy's age, w?

e ≥ 2w

Step-by-step explanation:

To make this easier, let us consider the case of Eliza being exactly twice as old as wendy

that would mean that twice the age of Wendy is the age of Eliza

e = 2w

but since she is AT LEAST twice as old as her, the age of eliza can be greater than twice of wendy and it might be equal to twice the age of Wendy

Hence, the symbol '=' will be replaced by '≥'

Hence, the correct relation is

e ≥ 2w
