The consult must make at least 600 dollars. That means the combination of reviews and new written pieces must be at least $600, or greater than or equal to (<span>≥) $600.
You are also told that each new piece = $120 and each review = $60. Let's use variables n = new piece and r = review. (You might be given different variables for your answer choices). That means the total money made from a combination of new pieces and reviews is: 120n (money made from each new piece times n number of new pieces) + 60r (money made from each review times r number of reviews).
Put that all together to get your inequality: 120n + 60r </span>≥ 600
