Continued from "All Gaga over Math".
Quick recap: Lady Gaga is doing a one-day concert in Tokyo. Concert sales need to be above $3 million to be profitable.
$1 million of concert sales will come from sponsorships. The rest must come from ticket sales, where tickets are $100 each. The number of tickets sold is y

Which of the following expressions describes this new scenario? (>= means ≥ and <= means ≤.)
100y >= 3 million
100y <= 3 million
