Final answer:
The correct equation describing Leo's total earnings including his hourly wage and the bonus is option A. 8.50h + 100 = Total earnings.
Step-by-step explanation:
The equation that represents Leo's total earnings when he works at McDonald's and receives a $100 bonus is:
A. 8.50h + 100 = Total earnings
This equation is set up to account for the hourly wage Leo earns, represented by 8.50h (where h is the number of hours worked), plus the $100 bonus he received for his store's inspection. So for every hour Leo works, he earns $8.50, and this is added to the $100 flat bonus to calculate his total earnings.
