If exactly 194 people sign up for a charter flight, Leisure World Travel Agency charges $312/person. However, if more than 194 p

eople sign up for the flight (assume this is the case), then every fare is reduced by $1 times the number of passengers above 194. Determine how many passengers will result in a maximum revenue for the travel agency. Hint: Let x denote the number of passengers above 194. Show that the revenue function R is given by R(x

Title:

<h2>The revenue will be maximum for 253 passengers.</h2>

Step-by-step explanation:

Let, the number of passenger is x, which is more than 194.

In this case, the travel agency will charge [312 - (x - 194)] per passenger.

The total revenue will be x[312 - (x - 194)] = 506x - x^{2}.

As x is the variable here, we can represent the revenue function by R(x). Hence, R(x) = 506x - x^{2}.

The revenue will be maximum when \frac{d (506x - x^{2} )}{dx} = 0\\2x = 506\\x = 253.

Eddi Din [679]
LW = 45
L + 2W = 19
L = 19-2W

substituting for L :-
W(19-2W) = 45

-2W^2 + 19W = 45

2W^2 - 19W + 45 = 0 
W = 5 or 4.5

If W = 5, L = 9
If W = 4.5, L = 10

So there are 2 possible answers.

Naddika [18.5K]

The domain of the linear function is (1.5, ∞) and the range of the linear function will be (40, ∞).

<h3>What are domain and range?</h3>

The domain means all the possible values of x and the range means all the possible values of y.

A carpet installer charges a flat rate of $40 and $1.50 per square foot for labor.

So the total cost for the labor depends on the amount of carpet installed, the relationship between the total cost for labor and the amount of corporate installed.

Then the domain of the relation is the range of the relation will be

Let y be the total amount and x be the number of square foot.

y = 1.5x + 40

Then the domain of the linear function is (1.5, ∞) and the range of the linear function will be (40, ∞).

The graph is given below.

More about the domain and range link is given below.
