Final answer:
Leo earns a total of $210.50 after working 13 hours at McDonald's with an hourly wage of $8.50 and receiving a $100 bonus.
Step-by-step explanation:
To calculate how much money Leo will earn after working 13 hours at McDonald's at a rate of $8.50 per hour and having received a $100 bonus for passing a store inspection, we can set up the following equation:
Total Earnings = (Hourly Wage × Hours Worked) + Bonus
Plugging in Leo's wage and hours, we get:
Total Earnings = ($8.50/hr × 13 hrs) + $100
Next, we calculate the total earnings:
Total Earnings = ($110.50) + $100
Total Earnings = $210.50
Therefore, after working 13 hours and receiving a $100 bonus, Leo will earn $210.50.
