5x^2+x-4
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:
We can derive R and equal to zero to maximize the function.
The amount of passengers is:
The price of the tickets is
The revenue is:
Answer:
$95 FOR A DRESS
Step-by-step explanation:
Let's rearrange the given:
She bought a blouse and skirt for two, a blouse and a dress for two, and a blouse for two.
A blouse and a skirt cost $107
A blouse and a dress cost $134
blouse cost x dollars
The equation:
2($107) + 2($134) + 2x = $560
SOLUTION:
$214 + $268 + 2x = $560
2x = $560 - $214 - $268
2x = $78
x = $39 for a single blouse
FIND THE COST OF DRESS:
A blouse and a dress cost $134 - $39 for a single blouse
$134 - $39 = $95
$95 IS THE COST OF DRESS
