For a two week period, john and amanda had the following transactions occur to their checking account: a deposit of $1,644.50; checks written for $190, $45, and $7.50; and debit card transactions for $30, $5.59, $7.20, and $21.30. what is the ending balance for this time frame?

deposit of $1644.50 is (gain)

check written and deposit are (loses)  subtracted

so total of 3 checks :-   190$   +  45$  +  7.50$   =   242.50$

total of 4 debit cards :-    30$  +  5.59$  +  7.20$  + 21.30$  = 64.09$

total lose amount ( credits + debits )  =   242.50 $  +  64.09$ =  306.59$

Ending balance = Total amount - total loses =  

         1644.50$ -  306.59 $ =  1337.91$
