SIMPLE COMMERCIAL DISCOUNT 1) A bill of R$ 70,000.00, with 90 days to expire, was discounted by a bank at the rate of 2.70% per month. Calculate the net amount delivered or credited to the customer. A: BRL 64,330.00.

The net amount delivered or credited to the customer can be calculated using the formula for simple commercial discount: Net Amount = Bill Amount / (1 + (Discount Rate * Time)) Given: Bill Amount (B) = R$ 70,000.00 Discount Rate (D) = 2.70% per month (expressed as a decimal: 0.027) Time (T) = 90 days / 30 days per month (since the rate is monthly) Net Amount = 70000 / (1 + (0.027 * (90 / 30))) Net Amount ≈ 64330 So, the calculated net amount is approximately BRL 64,330.00, which matches the given answer.
