Answer:
The correct option is b.
Step-by-step explanation:
Let the number of reviews be y and the number of new written pieces be x.
It is given that the consultant earns $80 for each new written piece and $40 for each review. The total earning is defined as
\(80x+40y\)
She make make at least $800 this week. It means she want make $800 and more than $800 this week. So the sign of inequality is ≥ instead of >.
\(80x+40y\geq 800\)
Therefore option b is correct.
