Karla scored 75, 80, and 92 on her history quizzes. What is the minimum score she needs on her next quiz to have a mean of 85?

The answer should be 93.

Step-by-step explanation:

So this took a lot of work to figure out, I did not solve it normally.

What i first did was add 75, 80, and 92 to get = 247. 247/3 was only 82, but in the equation you said the score on her next quiz, which means I would need to divide by 4.

But that was not possible with the numbers I had.

i started adding numbers to see if I would get the mean of 85, and eventually I added 93. to get 340, which I divided by 4 (the number of quizzes that were taken) to get the mean of 85.

so yeah, I made it more complicated than it need to be, but that's the answer lol
