Final answer:
The interest earned is $75, and the future value of the investment after 3 months is $15,075.
Step-by-step explanation:
To calculate the interest earned, we can use the formula: Interest = Principal x Rate x Time. In this case, the principal is $15,000, the rate is 2% (or 0.02 in decimal form), and the time is 3 months (or 1/4 of a year). Therefore, the interest earned is: $15,000 x 0.02 x 1/4 = $75.
To find the future value of the investment, we can use the formula: Future Value = Principal + Interest.
Interest = $75 (calculated in the previous step)
Future Value = $15,000 + $75 = $15,075.
