Final answer:
To calculate the earnings on the two jobs, we need to find the actual time taken for each job by multiplying the estimated time by 1.25. Then, we multiply the actual time for each job by the hourly wage to calculate the earnings. The total earnings on these two jobs would be $234.38.
Step-by-step explanation:
To calculate the total time it took for each job, we need to find the actual time taken, which is 1.25 times more than the estimated time. For hanging the blinds, the actual time is 5 hours and 30 minutes multiplied by 1.25, which equals 6.875 hours. For installing the tiles, the actual time is 2 hours and 30 minutes multiplied by 1.25, which equals 3.125 hours.
To calculate the earnings on these two jobs, we multiply the actual time for each job by the hourly wage of $23.50. So, for hanging the blinds, the earnings would be 6.875 hours multiplied by $23.50, which equals $160.94. For installing the tiles, the earnings would be 3.125 hours multiplied by $23.50, which equals $73.44.
Therefore, the total earnings on these two jobs would be $160.94 + $73.44 = $234.38.
