Luke has a credit line of $8,500 on his credit card. He had a previous balance of $4,236.87 and

Molodets [167]

Subtract the payment from the previous balance:

4236.87 - 3200 = 1036.87

Now add his total purchases:

1036.87 + 989.42 = 2026.29

This is the total amount he owes, now subtract that from his credit line:

8500 - 2026.29 = 6473.71

His available credit is $6,473.71
