Financial Maths Pop Quiz 1. Catherine is a sales assistant at a petrol station. She works 40 hours each week and is paid \( \$ 12.25 \) per hour. Calculate her equivalent monthly pay.

To calculate Catherine's equivalent monthly pay, we first need to determine her weekly pay and then convert that to a monthly amount. 1. **Calculate weekly pay:** \[ \text{Weekly Pay} = \text{Hourly Rate} \times \text{Hours Worked per Week} \] \[ \text{Weekly Pay} = 12.25 \, \text{USD/hour} \times 40 \, \text{hours/week} = 490 \, \text{USD/week} \] 2. **Convert weekly pay to monthly pay:** There are approximately 4.33 weeks in a month (52 weeks in a year divided by 12 months). \[ \text{Monthly Pay} = \text{Weekly Pay} \times 4.33 \] \[ \text{Monthly Pay} = 490 \, \text{USD/week} \times 4.33 \approx 2121.70 \, \text{USD/month} \] Therefore, Catherine's equivalent monthly pay is approximately **\$2121.70**.
