David invested $230 in a savings account that offers a 3% return on the investment. The value of David's investment will be at least $415 after a period of years.
Hint: Use the formula A = a1 + ', where A is the amount after tyears, Pis the amount invested, r is the rate of interest, and is the time period.
Use a calculator to compute the answer, and round it off to the nearest year.
