Section 3: Whoops, here's Tom again! Still doing it for $10 an hour. This time, he is asked to really bust his butt! He is asked to work 12 hours a day, for 7 days straight, to keep all the holiday shoppers happy. How much does he earn for the week?

He earns $840 for the week.

Explanation:

Wage rate = $10 per hour

Number of hours per day = 12 hours

Number of hours per week = 12 hours x 7 days

Number of hours per week = 84 hours

Total earning = Number of hours x Hourly rate

Total earning = 84 hours x $10 per hour

Total earning = $840

So, he now he earns $840 for a week by working 7 days a week and 12 hours each day.
