The inequalities that represent the possible combinations of reviews and newly written pieces that she must complete is 120x + 60y ≥ 720. The correct option is D.
What are inequalities?
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.
Let the number of written pieces be represented by x, while the number of reviews is represented by y.
Given that consultant earns $120 for each new written piece and $60 for each review. Also, the consultant needs to make at least $720 this week. Therefore, the total earnings of consultants should be always greater than or at least equal to $720. Thus, we can write the inequality as,
120x + 60y ≥ 720
Hence, the inequalities that represent the possible combinations of reviews and newly written pieces that she must complete is 120x + 60y ≥ 720.
