Divide 1000 by 25
Without taking interest into consideration, roughly 67 weeks.
100,000 weeks (approx 1,923 years)
The answer depends on the rate at which you can save. For example,: -- If you could save 5 every day, then your answer would be 800 / 5 = 160 days.
every second your body forms 1000 red blood cells
That depends on how much you are earning and how much you can afford to save. If you were earning $1000 a week, you could do it quickly. If you were earning $100 a week, it would take a lot longer. So there is no specific answer to the question.
It will take 1,000,000 divided by the average amount that you can save each day!
1000 divided by 80 = 12.5Hrs
