Answer:
I) Option 2)
II) Minimum 35 passengers must be carried in the flight to make a profit.
Step-by-step explanation:
We are given the following in the question:
I) Number of seats in plane = 295
Estimated cost = $3,845
Cost per passenger= $110 per hour of flight
Let x be the number of passenger travelling by flight.
Total cost =
![=\text{Total number of passengers travelling}\times \text{Cost per passenger}\\=110x](https://tex.z-dn.net/?f=%3D%5Ctext%7BTotal%20number%20of%20passengers%20travelling%7D%5Ctimes%20%5Ctext%7BCost%20per%20passenger%7D%5C%5C%3D110x)
Then, we can design the profit function as:
![P(x) = 110x - 3845](https://tex.z-dn.net/?f=P%28x%29%20%3D%20110x%20-%203845)
The domain is the collection \of all the values of x for which the function is defined.
Thus, the domain of the profit function will be
Option 2) ![0\leq x \leq 295](https://tex.z-dn.net/?f=0%5Cleq%20x%20%5Cleq%20295)
II) least number of passengers it must carry to make a profit
![P(x) > 0\\P(x) = 110x - 3845\\110x - 3845 > 0\\110x > 3845\\x > 34.95\\\Rightarrow x = 35](https://tex.z-dn.net/?f=P%28x%29%20%3E%200%5C%5CP%28x%29%20%3D%20110x%20-%203845%5C%5C110x%20-%203845%20%3E%200%5C%5C110x%20%3E%203845%5C%5Cx%20%3E%2034.95%5C%5C%5CRightarrow%20x%20%3D%2035)
Thus, minimum 35 passengers must be carried in the flight to make a profit.
Answer:
69 pounds
Step-by-step explanation:
5 x 42 = 210 - 20 = 190 Bobbi
3 x 42 = 126 - 5 = 121 Amira
190 - 121 = 69

Rs. 3,14,532
Step-by-step explanation:
Domain is all x value in which the graph is defined. In that case the domain will be:
(-1;infinity) or -1>x
