<human>:  Paul made two bank transfers of $90 and $60 respectively. A service charge of 2% was added to each transaction. If the second transaction was reversed (without the service charge), what is his account balance now if it was $400 before he made any of the transfers?
<bot>: How much is the service charge? ** 2% of $90 is (2/100)*$90 = $<<(2/100)*90=1.8>>1.8
How much is the service charge? ** 2% of $60 is (2/100)*$60 = $<<(2/100)*60=1.2>>1.2
How much was the second transaction reversed? ** The second transaction was reversed without the service charge so only a total of $90+$1.8+$1.2 = $<<90+1.8+1.2=93>>93 was deducted from his account
What is his account balance now? ** He will have a balance of $400-$93 = $<<400-93=307>>307
