We want to become millionaires attaining $2 million. Our 5th birthday is today, and our grandparents give us $10,000, which we invest at 5% interest rate. Additionally, they give us $4,000 for as long as we need it to attain our goal. Our retirement will start in 65 years last for 25 years and needs $70,000 per annum. We shall pay for a 4 year degree from our pocket in 13 years at $20,000 per annum. In year 8, we take a vacation to the Greek islands, and it costs us $26,000. How old shall we be when we attain our goal?
