Julio will receive $ 128 on the tenth day.

Given that Julio won a contest, and his cash prize is given to him in the following way: On the first day, Julio will receive $ 0.25, and for each successive day, the amount of money Julio receives doubles, to determine an explicit formula to represent the amount of money, f (d), in dollars, Julio receives d days after the first day, and determine how much money will Julio receive on the tenth day, the following calculations must be performed:

  • 0.25 x 2 ^ D = F
  • 0.25 x 2 ^ 9 = F
  • 0.25 x 512 = F
  • 128 = F

Therefore, Julio will receive $ 128 on the tenth day.
