Answer:
The first step is to calculate the interest that accrues over the 3-month period:
Interest = Principal x Rate x Time
= $4,000 x 0.075 x (3/12)
= $75
The amount due on the loan is the sum of the principal and interest:
Amount due = Principal + Interest
= $4,000 + $75
= $4,075
Rounding to the nearest cent gives: $4,075.00
