Solution Steps

Step 1: Calculate Unpaid Balance

The unpaid balance is calculated by subtracting the last payment from last month's balance: \[ \text{Unpaid Balance} = 530 - 210 = 320 \]

Step 2: Adjust Unpaid Balance

Next, we adjust the unpaid balance by adding purchases and subtracting returns: \[ \text{Adjusted Balance} = 320 + 293 - 561 = 52 \]

Step 3: Calculate Monthly Interest Rate

The monthly interest rate is derived from the annual interest rate: \[ \text{Monthly Interest Rate} = \frac{18\%}{12} = 0.015 \]

Step 4: Compute Finance Charge

Finally, the finance charge is calculated by applying the monthly interest rate to the adjusted balance: \[ \text{Finance Charge} = 52 \times 0.015 = 0.78 \]

Final Answer

The finance charge for the current month is \(\boxed{0.78}\).
