Answer:
Therefore his new balance=$712.95
Therefore his new balance is  =$ 930.44  
Step-by-step explanation:
Darnell starts the month $ 952.43 in his checking account. 
He buys an iPhone 7 for $ 217.49 with tax included and two kindle books that each $7.99.
The price of two books is =$(7.99× 2)= $ 15.98
Total amount that he paid for iPhone 7 and two books is =$(217.49+15.98)
                                                                                               =$233.47
Therefore his new balance = $(952.43- 233.47)
                                             =$712.95
The new iPhone 7 is not as awesome as promised , and Darnell returns it.
He will get the price of iPhone refund.
Therefore his new balance is $(712.95+217.49)
                                                 =$ 930.44
