Maria scored 72, 97, and 82 on her first three math tests. She wants to have a mean score of 82 for the quarter. How many points

Rom4ik [11]

Answer:

She needs 77 on her last test to earn an 82 for the quarter.

Step-by-step explanation:

Maria scored 72, 97, and 82 on her first three math tests.

She wants to have a mean score of 82 for the quarter.

Let us assume that she must score x on her last test to earn an 82 for the quarter.

So the average score will be,

$=\dfrac{72+97+82+x}{4}$

But the average score is given as 82, so

$\Rightarrow \dfrac{72+97+82+x}{4}=82$

$\Rightarrow 72+97+82+x=82\times 4$

$\Rightarrow 72+97+82+x=328$

$\Rightarrow x=328-72-97-82$

$\Rightarrow x=77$
