Final answer:
Donald's gross income for the pay period is $1378.49.
Step-by-step explanation:
Donald's gross income can be calculated by adding the net income from both jobs and the tax withholdings for each job.
Gross income = [Net income job 1 + Tax withholding job 1] + [Net income job 2 + Tax withholding job 2]
Gross income = [$545.89 + $92.01] + [$619.10 + $120.49]
Gross income = $638.90 + $739.59
Gross income = $1378.49
Therefore, Donald's gross income for the pay period is $1378.49.
