Final answer:
To find the loan's effective annual rate (EAR), calculate the amount borrowed after the interest is added and the monthly installment payments. The EAR formula is (1 + Monthly Interest Rate)^12 - 1.
Step-by-step explanation:
To find the loan's effective annual rate (EAR), we need to first calculate the amount borrowed after the interest is added, and then determine the monthly installment payments. The formula to calculate the amount borrowed after six months is:
Amount Borrowed = Principal + (Principal * Interest Rate * Time)
Using the given values, we can substitute them into the formula:
Principal = $750,000
Interest Rate = 10% = 0.10
Time = 6 months
After finding the amount borrowed, we can determine the monthly installment payments by dividing the total amount borrowed by the number of months:
Monthly Installment = Amount Borrowed / Time
Finally, to find the loan's effective annual rate (EAR), we can use the formula:
EAR = (1 + Monthly Interest Rate)12 - 1
Where Monthly Interest Rate = Interest Rate / 12
By substituting the given values, we can calculate the EAR.
