In Problems 79-82, assume that the annual interest rate on a credit card is 25.74 % and interest is calculated by the average daily balance method. The unpaid balance at the start of a 28 -day billing cycle was $ 1 , 837.23 . Purchases of $ 126.54 and $ 52.89 were made on days 21 and 27 , respectively, and a payment of $ 100 was credited to the account on day 20 . Find the unpaid balance at the end of the billing cycle.

answer is correct.
Find the bisector of the angle <ABC in the Poincaré plane, where A=(0,5), B=(0,3) and C=(2,\sqrt{21})
The masses measured on a population of 100 animals were grouped in the
following table, after being recorded to the nearest gram
