The average of 5, 7, 12, and 12, is (5 + 7 + 12 + 12)/4.
(5 + 7 + 12 + 12)/4 = 36/4 = 9.
The average is 9.

To find the average, or mean, you add up all the numbers and divide the sum by the total number of numbers you added up.

5, 7, 12, 12
Add these numbers up ⇒ 5 + 7 + 12 + 12 = 36.
Divide 36 by the number of numbers added up, 4. ⇒ 36 ÷ 4 = 9

The mean of the numbers is 9.

Amount $100,000

sergey [27]

Answer:

1) Repaid for the loan = $239,511.60

2) Percentage = 58.2%

3) Average amount = $387.53

Step-by-step explanation:

Given :

Amount $100,000

Rate 7%

Payments 360 - $665.31

Total interest $139,511.60

To find :

1) How much will be repaid for this loan?

Repaid for the loan = Amount - Total interest

Repaid for the loan = 100,000 + 139,511.60

Repaid for the loan = $239,511.60

2) What percentage will be repaid for this loan?

$\text{Percentage}=\frac{\text{Total interest}}{\text{Repaid loan}}\times100$

$\text{Percentage}=\frac{139511.60}{239511.60}\times100$

$\text{Percentage}=0.582\times100$

$\text{Percentage}=58.2\%$

3) What will be the average amount per payment for interest?

$\text{Average amount}=\frac{\text{Total interest}}{\text{Payments}}$

$\text{Average amount}=\frac{\text{139511.60}}{\text{360}}$

$\text{Average amount}=387.53$
