If exactly 180 people sign up for a charter flight, Leisure World Travel Agency charges $298/person. However, if more than 180 p

lesantik [10]

Answer:

The max. revenue is $57,121.

This happens with 239 passengers.

The price of the ticket is $239 per person.

Step-by-step explanation:

Let the variable "P" denote the number of passengers.

If P=180, then the ticket cost is $298/person. Then the price is reduced by $1 for each additional person.

In general, if P=(180+x), then the ticket cost becomes (298-x) per person.

The revenue can be defined as the ticket cost multplied by the number of passengers:

$R=P*T=(180+x)(298-x)=53,640-180x+298x-x^2\\\\R(x)=-x^2+118x+53,640$

We can derive R and equal to zero to maximize the function.

$dR/dx=-2x+118=0\\\\x=118/2=59$

The amount of passengers is:

$P=180+x=180+59=239$

The price of the tickets is

$T=298-59=239$

The revenue is:

$R(59)=(180+59)(298-59)=239*239\\\\R(59)=57,121$

Diane has $1.40 in dimes and nickels. She has a total of 16 coins. How many of each kind does she have?

Kazeer [188]

9514 1404 393

Answer:

4 nickels
12 dimes

Step-by-step explanation:

Let d represent the number of dimes. Then 16-d is the number of nickels, and the total value is ...

0.10d +0.05(16 -d) = 1.40

0.05d + 0.80 = 1.40 . . . . . . . eliminate parentheses

0.05d = 0.60 . . . . . . . . subtract 0.80

d = 12 . . . . . . . .dimes

(16 -d) = 4 . . . . nickels

Diane has 12 dimes and 4 nickels.
