Final answer:
To find the present interest rate on a variable interest loan, add the margin of 1.9% to the prime rate of 5.2%, which totals to 7.1%. Therefore correct option is D
Step-by-step explanation:
The interest rate on a variable interest loan can be determined by adding the margin to the index rate,
in this case, the prime rate. With the margin given as 1.9% and the prime rate currently at 5.2%, the present interest rate on the loan would be the sum of these two figures.
To calculate: 1.9% (margin) + 5.2% (prime rate) = 7.1% (total interest rate).
Therefore, the current interest rate on the variable interest loan is 7.1%.
