Final answer:
Harry's new hourly salary is C)$9.00.
Step-by-step explanation:
To find Harry's new hourly salary, we need to calculate his salary per hour before and after the changes.
Before the changes, Harry earns $360 per week for a 44-hour work period. So his hourly salary is $360 / 44 = $8.18 rounded to the nearest cent.
After the 10% increase in salary, his new weekly salary is $360 + 10% of $360 = $396. His hours are reduced by 10%, so his new work period is 44 - 10% of 44 = 39.6 hours. Therefore, his new hourly salary is $396 / 39.6 = $10. The correct answer is C. $9.00.
