Derrick statement shows a previous balance of 3264.75 a payment of 180 and a new transaction totalling 134 what is his new balance if his apr is 13.2%

To compute for the Derricks new balance:

New balance= previous balance + interest of previous balance-payment +new transaction
where
previous balance = 3264.75
interest of previous balance = 3264.75x(APR/12)=35.91225
APR=13.2%/12, 1.1%
payment= 180
new transaction= 134
new balance = 3254.66225
