3)Principal Amount = P = $7200
Interest rate = r = 4% = 0.04
Time = t = 8 years
Formula for compounding is:

Using the values, we get:

Therefore, the compounded amount will be $9853.70
4)Principal Amount = P = $7200
Compounded Amount = A = $9853.70
Interest Earned = Compounded Amount - Principal Amount
So,
Interest Earned = 9853.70 - 7200 = $2653.70
Therefore, $2653.70 will be earned as interest over a period of 8 years.

Answer:
$1,700
Step-by-step explanation:
Given the following :
Period of mortgage = 25 years
Mortgage amount = $130,000
Total interest on mortgage = $380,000
Hence,
Total amount to be paid ( principal + interest) :
($130,000 + $380,000) = $510,000
Total number of months over the 25 years period:
25 × 12 = 300 months
Payment per month:
Total repayment / number of months
= $510,000 / 300
= $1,700 per month
