235$ and if you withdraw 20$ on three days thats 60$ so if we remove that from the account we have 175$ left.
Then on Friday when he got paid he put 130$ into the bank he has 175+130=305$
If he wrote a check 1 for 167$ and 1 for 212$ thats his account balance - 212 then -167 = 305 -378 so he has a balance of -73
