Final answer:
Kim will accrue $1,495.20 in interest over the 4.5 year nonpayment period on her federal unsubsidized student loan amounting to $7,900 at an interest rate of 4.29%.
Step-by-step explanation:
To calculate the amount of interest Kim will accrue during the 4.5 year nonpayment period on her $7,900 federal unsubsidized student loan at a rate of 4.29%, we use the simple interest formula:
Interest = Principal × Rate × Time
Here, the principal is $7,900, the rate is 4.29% (or 0.0429 when expressed as a decimal), and the time is 4.5 years.
Plugging the numbers into the formula gives:
Interest = $7,900 × 0.0429 × 4.5
Interest = $1,515,655
This means that the correct answer is (b) $1,495.20.
