A second law firm states that their legal fees can be determined using the expression 440x + 17000. The company president wants to know when the legal fees would cost the same for each law firm. What number of hours of legal assistance makes the equation 380x + 25000 = 440x +17000 true? Round your answer to the nearest whole number.

Accepted Solution

A:
Answer:For x = 133 hours of legal assistance both the firms charges the same amount of legal fees.Step-by-step explanation:In LAW FIRM FIRST:The legal fees is of the form: 380 x + 25000, where x is the number of hours of legal assistance.In LAW FIRM SECOND:The legal fees is of the form: 440 x + 17000, where x is the number of hours of legal assistance.Now, let us assume for x working hours, both firm charges the same amount.⇒380 x + 25000 = 440 x +17000Solving for x, we get: 25,000  - 17,000  = 440 x  - 380 xor, 60 x  = 8,000or, x  =   8000/60 = 133.33or, x is approximately equal to 133 hours. Hence, for x = 133 hours of legal assistance both the firms charges the same amount of legal fees.
