West deposited $15,000 in a savings account earning 2.5% simple interest what was the total interest earned at the end od 8 years

2.5% of 15,00$ would be 375$. Assuming the "simple interest" is yearly, you would multiply 375 by 8, which is 3000$ :P (Another way to solve this would be to multiply the 2.5 by 8, which would be 20. and 20% of 15,000$ would also be 3,000$)

3,000 dollars is your answer.
