Question 894567
Will you please help me with my math word problem. I tried every solution and I do not know how my professor got different answers than mine. 

Luke L. owes $386.43 on his Visa account. He returns two items costing $22.02 and $31.63 for credit. Then he makes purchase of $49.00 and $95.44.

A. How much should his payment be if he wants to pay off the balance on the account? 

B. Instead of paying of the balance, he makes a payment of $300 and then incurs a finance charge of $24.23. What is the balance (amount owed) on his account?
----------------------------------------------

According to my professor the answer to letter A is $477.22.
My answer was $406.30
I do not know how my professor got the answer.

For Letter B I answered $-19.87 and he answered 201.45.

Will you please help me understand how he got the answers. Thank you.
