If your employer asked you to select one of these options: a) your salary for the next two months will be $5,000, b) 1 penny for the first day and then he will double your salary every day for the entire month, which one should you pick? how much will you have at the end of 30 days?

To know what type of salary will give a higher pay, we calculate our earnings per month. For option 1, we will 5000/2 months or 2500/month. For option 2, we will have an increasing salary everyday for the entire month. If we have 30 days of work per month, then we will have a salary of  536870912/month. Therefore, the best option is the second one.
