In a song competition, a participant has to score a total of at least 20 points in the first four rounds combined to move on to the fifth and final round. Curtis scored 2 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Curtis scored in each of the second, third, and fourth rounds if he earned a place in the finals? 2 + 3p ≤ 20 2p + 3 ≥ 20 2 + 3p ≥ 20 2p + 3 ≤ 20

At least a, that means a is the smallest one. In other words, a < = something. From this argument, you can get rid off 2 options. Which ones are left??

OpenStudy (anonymous):

b and c?

OpenStudy (loser66):

OpenStudy (loser66):

Now, between b and c, we need choose the correct one.
