We want to become millionaires. Our 10th birthday is today, and our grandparents give us $15,000, which we invest at 5% interest rate. We shall pay for a 4 year bachelor’s from our pocket in 8 years at $30,000 per annum. In year 16, we take a vacation to the Greek islands, and it costs us $20,000. We put aside $3,000 per annum.
How old shall we be when we attain our goal?
