Answer: interest = $ 3,629.34

Step-by-step explanation:

Complete question

(Marlie will be starting college next year, federal unsubsidized student loan in the amount of $18,800 at 4.29%. She knows that during this non-payment time, interest will accrue at 4.29%. Suppose Marlie only paid the interest during her four years in school and the six-month grace period. What will she now pay in interest over the term of the loan.)

This question relates to interest over a single period of time and since it's not compounded, we use formula for simple interest to calculate the interest accrued.

Data;

P = $18,800

R = 4.29% = 0.0429

T = 4.5 years

S. I = ?

S. I = PRT

S. I = 18,800 * 0.0429 * 4.5

S. I = $3,629.34

Therefore she'll need to pay $3,629.34 as interest accrued.
