they are Divide 360 by the difference of the angle and 180 degrees. For the example, 360 divided by 15 equals 24, which is the number

179.99x 6%= 10.79      179.99 +10.79=190.78                                                190.78 - 62.50=128.28 dollars that Brandon still needs to buy the baseball hat. 31.25 x 4=125.00 which is not enough. 31.25x5=156.25 so it will take Brandon another 5 weeks to save the rest of the money for the hat.
