$ 25 was the cost of each ticket before applying the service fee.
<u>Step-by-step explanation:</u>
Given that the cost of two tickets including the service fee = $59
So, the cost of one ticket including the service fee = 
Service fee on each ticket = 18%
Let the cost of 1 ticket without including the service fee = x
So, according to the data given in the question,





Hence, cost of each ticket before applying the service fee = $25
For c to be positive, and for b to be negative, m must be negative and n must be negative.
X^2 - bx + c = (x - m)(x - n).
c is the product of m and n. If both m and n are positive, c would be positive. However b is the sum of m and n, therefore to make b negative, both m and n must be negative to ensure that the product of m and n is positive
Answer:
273.38
Step-by-step explanation:
815.70 * 6.2% = 50.57
815.70 * 1.45% = 11.83
815.70 * 19% = 154.95
Add those 3 totals to the additional $56 in federal tax
56+50.57+11.83+154.95 = 273.35
