$ 5,093.57

Step-by-step explanation:

Amount on credit line $6,500

Adding the previous balance of $ 398.64

Total amount of credit = $ 6,898.64

We subtract payment of $ 250 n

That is ; $ 6,898.64 - $ 250

                 = $ 6,648.64

Then

We subtract purchases of $ 1,257.99

That is;  

 = $ 6,648.64 - $1,257.99

 = $ 5,093.57
