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.

Find the savings plan balance after 18 months with an APR of 3% and monthly payments of $200.
ArbitrLikvidat [17]

The saving plan balance is $3,677.53.

Given that,

  • The no of months is 18.
  • The annual percentage rate is 3% so the monthly rate percentage is 0.25%.
  • And, the monthly payment is $200.

Based on the above information, the following formula should be used:

FVA = PMT×  [(1+r)^n - 1] ÷ r

= $200 × [(1+ 0.0025)^18 - 1] ÷ 0.0025

= $3,677.53

Therefore we can conclude that the saving plan balance is $3,677.53.
