Final answer:
The correct answer is option D. The employee will earn $13.20 per hour for the time worked between 6:00 PM and 12:00 AM. This is calculated by adding the additional 10% wage increase to the base pay of $12.00 per hour, resulting in an additional $1.20 per hour.
Step-by-step explanation:
The employee will make $13.20 per hour between 6:00 PM and 12:00 AM. To calculate this, we need to compute the additional 10% increase to the base rate of $12.00. The percentage increase is calculated as follows:
Additional pay per hour = Base rate x Percentage increase
Additional pay per hour = $12.00 x 10%
Additional pay per hour = $12.00 x 0.10
Additional pay per hour = $1.20
So, to find out the new wage per hour, add this additional amount to the base rate:
New wage per hour = Base rate + Additional pay per hour
New wage per hour = $12.00 + $1.20
New wage per hour = $13.20
This means for every hour worked between 6:00 PM and 12:00 AM, the employee will earn $13.20.
