B.120yx+60y(=<)720

C.120x+60y<720

D,120x+60y(=>)720

equal or greater than or equal or less than is not on the keyboard

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.
