Final answer:
To calculate how much parent 1 earned from work in 2021, you need specific information on their salary or hourly rate and the number of hours worked. A calculation example is provided.
Step-by-step explanation:
To determine how much parent 1 earned from work in 2021, you would need the specific information on their salary or hourly rate, as well as the number of hours worked. Let's say parent 1 earns $20 per hour and works 40 hours per week. To calculate their earnings for a year, you can multiply their hourly rate by the number of hours in a week (40) and then multiply that by the number of weeks in a year (52).
Earnings = Hourly Rate x Hours per Week x Weeks per Year
Earnings = $20 x 40 x 52
Earnings = $41,600
Therefore, if parent 1 earns $20 per hour and works 40 hours per week, their total earnings for the year would be $41,600.
