To find the missing values, we need to calculate the hourly rate that Jairo is being paid. We can do this by dividing the amount of money earned by the number of hours worked.
First, let's calculate the hourly rate using the given values:
Hourly rate = Amount of money earned / Number of hours worked
Hourly rate for 2 hours = $32 / 2 = $16 per hour
Hourly rate for 4 hours = $64 / 4 = $16 per hour
Hourly rate for 7 hours = $176 / 7 ≈ $25.14 per hour
Hourly rate for 12 hours = $192 / 12 = $16 per hour
Now, to fill in the missing values:
For 7 hours of work, the amount earned would be:
Amount earned = Hourly rate * Number of hours worked
Amount earned = $25.14 * 7 ≈ $175.98
Therefore, the missing value in the amount of money earned for 7 hours of work is approximately $175.98.
For the last missing value, since it's for 9 hours of work, we can use the hourly rate to calculate it:
Amount earned for 9 hours = Hourly rate * 9
Amount earned for 9 hours = $25.14 * 9 ≈ $226.26
Therefore, the missing value for 9 hours of work would be approximately $226.26.
