Calculation of the Teacher's Work Hours

To calculate the number of hours the teacher will work on Saturday, we need to consider the total number of hours the teacher works in a week and the number of hours worked from Monday to Friday.

According to the given information, the teacher's workload is 26 hours per week, and they work from Monday to Saturday. From Monday to Friday, the teacher works for 4.5 hours each day.

To find the number of hours the teacher works on Saturday, we can subtract the total hours worked from Monday to Friday from the total weekly workload.

Let's calculate it step by step:

1. Calculate the total hours worked from Monday to Friday: - The teacher works for 4.5 hours each day from Monday to Friday. - So, the total hours worked from Monday to Friday = 4.5 hours/day * 5 days/week = 22.5 hours/week.

2. Calculate the number of hours the teacher will work on Saturday: - The total weekly workload is 26 hours. - Subtract the total hours worked from Monday to Friday from the total weekly workload: 26 hours - 22.5 hours = 3.5 hours.

Therefore, the teacher will work for 3.5 hours on Saturday.
