Juana’s dad gave her an exponentially increasing allowance as an experiment. On the first day, he gave her 1¢. On the second day he doubled it and gave her 2¢, and on the third day, he doubled that and gave her 4¢. He kept doubling the previous day’s amount for a total of 10 days. How much did he give her on the tenth day?
