To find out how much Bashir makes in 15.5 hours, we can use linear interpolation.
First, we need to calculate the hourly rate for each data point:
- For 15 hours, the hourly rate is $228 / 15 = $15.20 per hour
- For 23 hours, the hourly rate is $349.60 / 23 = $15.20 per hour
- For 33 hours, the hourly rate is $501.60 / 33 = $15.20 per hour
Since the hourly rate is the same for all data points, we can calculate his earnings in 15.5 hours:
Earnings = $15.20 per hour * 15.5 hours = $235.60
Therefore, Bashir makes $235.60 in 15.5 hours.
The table below shows Bashir's earnings on the job.
