Question

A consultant needs to make at least $720 this week. She earns $120 for each new written piece and $60 for each review. Which of the following inequalities represent the possible combination of review and written pieces that she must complete?

 

A.) 120x + 60y <= 720

 

B.) 120x + 60y >= 720

 

C.) 120x + 60y < 720

 

D.) 120x + 60y > 720

Answer 1

Actually B is correct. The money made is on the left side of the inequality

B.) 120x + 60y ≥720

You want the money made to be at least $720. This means the money made should either be greater than or equal to $720.

The larger side of the inequality corresponds to the larger side of the less than or equal to sign.

 

1<2     :you can think there is one point on the left and two points on the right of the symbol.

 

 

Answer 2

A is correct

 

Since it is --- at least 720
