Final answer:
To calculate the total income for last week, we need to account for the extra hours worked at time-and-a-half on top of the regular earnings. The employee's total income for last week, including regular pay and overtime, was $1005.70.
Step-by-step explanation:
To calculate the total income for last week, we need to account for the extra hours worked at time-and-a-half on top of the regular earnings. First, we calculate the overtime pay rate, which is 1.5 times the regular hourly rate of $22.60. This gives us $22.60 * 1.5 = $33.90 per overtime hour. The employee worked 3 overtime hours, so the total overtime pay is $33.90 * 3 = $101.70. The regular weekly earnings are $904, so we add the overtime pay to this amount to get the total earnings for the week: $904 + $101.70 = $1005.70.
