Hm...

OpenStudy (anonymous):

Well, he has to have at least 210, so do you think it will be less than or equal to 210 or greater than or equal to 210?

OpenStudy (anonymous):

...less than or equal?

OpenStudy (anonymous):

No. Look, he has to have at least 210, which means he has to have 210 or more. If he had less than 210, he couldn't buy the phone, so it is \(\geq\)

OpenStudy (anonymous):

Or greater than or equal to :)

OpenStudy (anonymous):

Ah okay. Thanks

OpenStudy (anonymous):
