Noah scored 20 points in a game. Mai's score was 30 points. The mean score for Noah, Mai, and Clare was 40 points. What was Clare's score? Show your work.
I need this answer ASAP.

Answer:

Clare's score was 70.

Step-by-step explanation:

N = 20

M = 30

C = ?

Mean = (Sum of all values)/3

40 = (20 + 30 + c)/3

40 = (50 + c)/3

50 + c = 120

c = 70

Answer:

70

Step-by-step explanation:

Let's think about this backwards. The mean of all 3 points is 40, so that is our answer. We instead of dividing would multiply. We would multiply by 3 'cause that's how many numbers there are. We would get 120. Finally, we would                                                                                                    

                                                                                      3

have to subtract. We will do this problem:

20 + 30 = 50

120 - 50 = 70

So, we get our answer of 70!

Let's check our work!

20 + 30 + 70 = 120 = 40

         3               3

__

Let's explain our work propproperly:

First, I took the mean and multiplied it by three because we have Noah, Mai, and Clare. Next, I added 20 and 30 to get an answer of 70 which is the answer. In conclusion, Clare's points are 70 points.
