Answer:Therefore, Dianne earns ₱62,300 in a month working 8 hours from Monday to Friday and 4.50 hours on Saturday at a rate of ₱350 per hour.Step-by-step explanation:To calculate Dianne's monthly earnings, we need to determine the total number of hours she works in a month and then multiply that by her hourly rate. Given: - Dianne works 8 hours from Monday to Friday = 8 hours/day x 5 days = 40 hours- Dianne works 4.50 hours on Saturday Total hours worked per week = 40 hours (Monday to Friday) + 4.50 hours (Saturday) = 44.50 hours/week To find the monthly earnings: - Multiply the total hours worked per week by the number of weeks in a month (assuming 4 weeks in a month)- Then multiply the total hours by the hourly rate of ₱350 Let's calculate:Total hours worked per month = 44.50 hours/week x 4 weeks = 178 hours Monthly earnings = 178 hours x ₱350/hour = ₱62,300
