Answer:Here's how to calculate the teacher's commission: 1. Identify the commission rate: - The commission rate is 5%. 2. Determine the total sales amount: - You need the total sales amount made by the teacher to calculate the commission. This information is missing from the problem. 3. Calculate the commission: - Multiply the total sales amount by the commission rate:- Commission = Total Sales Amount * Commission Rate Example: Let's say the teacher sold appliances worth 10,000 pesos. Here's how to calculate the commission: - Commission = 10,000 pesos * 0.05 = 500 pesos Therefore, the teacher's commission would be 500 pesos if he sold 10,000 pesos worth of appliances. Important Note: You need the total sales amount to calculate the exact commission.
