Final answer:
To determine the amount charged to each job, we need to know the specific earnings for each job.
Step-by-step explanation:
To determine how much of the $840 that Joyce earned during this week would be charged to job 271, job 272, and job 273, we need to know the specific amounts that Joyce earned for each of these jobs. Without knowing the breakdown of her earnings by job, we cannot determine the exact amount charged to each job. If you can provide the earnings for each specific job, I can help you calculate the amounts charged to job 271, job 272, and job 273.
