Answer:
The amount was made by the firm is $ 300.
Step-by-step explanation:
Given,
The paralegal worked for a client for 5 hours per day for 3 days,
So, the total number of hours for which the client paid = 5 × 3 = 15 hours,
Now, the client was billed $50 per hour,
Thus, the total amount paid by client = 15 × 50 = $ 750,
The paralegal was paid $30 per hour.
The amount paid to paralegal = 15 × 30 = $ 450,
Hence, the amount made by the law firm = The total amount paid by client - The amount paid to paralegal
= $ 750 - $ 450
= $ 300
