Anna [14]

Answer:

89.

Step-by-step explanation:

We have been given that after taking 7 quizzes, your average is 77 out of 100. We are asked to find what average score be on the next five quizzes to increase your average to 82.

The total of 12 quizzes to get 82 would be $12\times 82=984$ .

The total scores earned by you in previous 7 quizzes are $7\times 77=539$

The total scores you need to earn on next 5 quizzes would be difference of scores in 12 quizzes and total scores in 7 quizzes as:

$984-539=445$

Now, we will divide total scores on coming 5 quizzes by 5 to find the average as:

$\text{Average score on next 5 quizzes}=\frac{445}{5}$

$\text{Average score on next 5 quizzes}=89$

Therefore, your average score on the next five quizzes should be 89 to increase your average to 82.

First, make all the fractions have the same denominator. That would make 39/6 + 50/6. Then, just add the tops together, and your answer is 89/6.
