Answer:
Annual interest rate = 6%
Explanation:
Amount of loan = $25,000
The total amount repaid:
($7,000 × 3 years) + ($10,000 balloon payment)
= (7,000 × 3) + (10,000)
21,000 + 10,000 = $31,000
Interest on payment = repayed amount - loaned amoun
Interest on payment = 31,000 - 25,000 = $6,000
Let the total percentage on the loaned amount be x
Therefore we are looking for what percentage rate of the loaned amount ($25,000) will give the interest of $6,000
x % of 25,000 = 6,000
[tex]\frac{x}{100} \times\ 25,000 = 6,000\\\frac{25,000x}{100} = 6,000\\25,000x = 600,000\\x = \frac{600,000}{25,000}\\x = 24[/tex]
Therefore the total percentage interest rate = 24%
Annual interest rate = Total interest rate ÷ number of years
Annual interest rate = 24 ÷ 4 = 6%
∴ Annual interest rate = 6%
