Final answer:
Aquaman will earn $510 for working 8 hours at the recreation center, based on the pay rate of $350 plus $20 per hour. However, this correct calculation does not match any of the provided answer choices, indicating a possible error in the question's options.
Step-by-step explanation:
The student has asked how much Aquaman will be paid for working 8 hours at a recreation center, where the pay rate is $350 plus $20 per hour. To calculate his total earnings before tax, we multiply the number of hours worked (8 hours) by the hourly rate ($20) and then add the fixed amount ($350).
Total earnings = $350 + ($20 × 8 hours)
Total earnings = $350 + $160
Total earnings = $510
However, this total is not listed in the options provided. It seems there was a mistake in the options or in the initial question details. Based on the given options, if Aquaman works 8 hours, the correct computation without considering tax deductions is: $350 base pay plus $20 per hour for 8 hours, which equals $510 total. None of the provided options (A) $190, (B) $490, (C) $430, (D) $250 are correct based on the given pay rate and hours. Therefore, it seems that there may be some error in the options provided in the question.
