Question

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?

Answer 1

Answer:

$2+3p\geq 20$

Step-by-step explanation:

Given that 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 I round.  He then went on to score additional points in the second, third, and fourth rounds

Let p be the identical point in II, III and IV round.

Then total of four rounds Curtis scored = 2+3p

Since he got selected for the finals, we have

$2+3p\geq 20$

Answer 2

20=2+p
p=18 divided by 3
p=6
