Fixed price costs
Crew salaries 350
fuel 120
overheads 170
Total fixed cost: 640
Variable costs per passenger
refreshments $ 6.50
refund $ 3.64
total variable cost: 10.14
Sales income
<span>Average ticket $ 36 .40
</span><span>Break-even point = <u> (fixed costs) </u>
(income per passenger – costs per passenger) </span><span>

Break even = 640 / (36.40-10.14) = 640 / 26.26 = 24.37
Answer:

Step-by-step explanation:
Given:
The given inequality is:

The given inequality has variable 'x' on both sides of the inequality.
In order to solve such inequalities, we bring the variables on the same side as the first step in solving for 'x'.
Therefore, we could either add
on both sides or add
both sides to bring the variable terms on same side.
If we add
both sides, we get:

So, among all the given options, third option matches the above inequality.
Therefore, the first step in solving the given inequality is 
Answer:
B. A value of x = 27 results in congruent triangle.
