Hello there :)
The answer to your question is oncogene.

Given the problem above, let's compute both loans first in order to compare which is which.
Loan A $5,000 with 3.5% interest to be paid for four years
Loan B $5,000 with 3.5% interest to be paid for six years
Let's solve for the 3.5% of 5,000 so it will be 175. So every year, there is an interest of $175 per year.
so for loan A, $5000 + 175(4) = $5700
Loan B, $5,000 + 175(6) = $6,050
Based on the given results, it is loan B that will have a higher cost.
