At 5 cents a minute, calling his father cost Freddy 5* 45 = <<5*45=225>>225 cents.
At 25 cents a minute, calling his brother cost Freddy 25 * 31 = <<25*31=775>>775 cents.
Adding the cost of calling his father and brother, we find that Freddy paid a total of 225 + 775 = <<225+775=1000>>1000 cents.
Since each dollar has 100 cents, Freddy paid 1000 / 100 = <<1000/100=10>>10 dollars
