Help how to do it because this is hard

If he gets paid $315 per week, and he has to pay the agency 40% of his first 5 weeks’ pay:

Multiply $315 by 5 weeks to determine how much is his 5-weeks’ worth of work:

$315 × 5 weeks = $1,575.

Next, we need to multiply $1,575 by 40% or 0.40 to determine the agency’s fee:

$1,575 × 0.40 = $630

40% of Enid’s 5-week pay = $630.

Therefore, Enid must pay the employment agency $630.
