Final answer:
Yaritza's rate of pay is calculated by dividing the total earnings by the number of hours worked for each dataset. After calculations, it is determined that Yaritza earns $19.70 per hour consistently.
Step-by-step explanation:
The question asks us to find Yaritza's rate of pay in dollars per hour based on the given information. To do this, we'll calculate the hourly wage for each set of data provided and see if they match. The data given shows the number of hours worked and the corresponding total earnings. The formula for finding the hourly rate is total earnings divided by the number of hours worked.
- 8 hours −> $157.60: $157.60 ÷ 8 hours = $19.70 per hour
- 23 hours −> $453.10: $453.10 ÷ 23 hours = $19.70 per hour
- 32 hours −> $630.40: $630.40 ÷ 32 hours = $19.70 per hour
After performing the calculations, we can see that Yaritza is earning $19.70 per hour consistently across the different hours worked. Therefore, the rate of pay is $19.70 per hour.
