Final answer:
Enid will pay $630 to the employment agency, which is 40% of her earnings for the first five weeks at $315 per week.
Step-by-step explanation:
Enid has to pay a fee equal to 40% of the first five weeks' pay to the employment agency. Given her weekly pay is $315, first, we calculate the total pay for five weeks:
Total pay for five weeks = 5 weeks * $315/week = $1575
Next, we calculate 40% of this amount to determine the agency fee:
Agency fee = 40% of $1575 = 0.40 * $1575 = $630
Therefore, Enid will have to pay $630 to the employment agency if she gets the job.
