To find which equation show the exact answer, Becasue he need at least 50 poitns to have a B, so:

4x + 8y must larger or equal to 50

In these choice, some I can't figure out what it means but the correct answer for this is:

4x + 8y = 50 or 4x + 8y > 50

Hope this help you :3

Answer 2

Answer:

4x + 8y ≥ 50

Step-by-step explanation:

Since x represents the multiple choice questions, and each of them is worth 4 points, the total points because of this type of questions is

4x

and y represents the word problems, and each of this is worth 8 point, so the total points because of this type of questions is

8y

Lorenzo needs at leat 50 points: this means 50 points or more, so the sum of the points he gets for each type of question must be equal to 50 points or more.

This is represented by the inequation:

4x + 8y ≥ 50
