Your answer is - 2 - 4n - 8n² after you combine like terms.
Answer:
a) At $3,300 for 600 seats, the average price per seat is 3300/600 = $5.50. The mix of tickets that results in that average can be found using an X diagram as shown below. The numbers on the right are the differences along the diagonals. When they are multiplied by 2, they add to 600. This shows that the required sales for revenue of $3,300 are
200 adult tickets
400 student tickets
b) When 3 student tickets are sold for each adult ticket, the average seat price is
(3*$4.50 +7.50)/4 = $5.25
Then the shortfall in revenue is ...
$3,300 -480*$5.25 = $780
Find the MPH of the boat when it goes upstream... 3h / 6m = 1h / 2m
So, 2mph
Speed of the boat - current = 2mph - > x - y = 2
Find the MPH of the boat going downstream... 3h / 18m = 1h / 6m
So, 6mph
x + y = 6
We now have a system of equation, let's solve it!
x - y = 2 -> x = y + 2
x + y = 6 - > (y + 2) + y = 6 -> 2y + 2 = 6 -> 2y = 4 -> y = 2
This is the speed of the current!
Subtitute y = 2 in the first equation:
x - 2 = 2
x = 4
This is the speed of the boat
Rate of the current = 2mph
Rate of the boat in still water = 4mph

Answer:
cost for adults: 2×$12.50
cost for children: 3×$8.00
total cost: 2×$12.50 +3×$8.00
$49.00
Step-by-step explanation:
Assuming I, my brother, and my sister qualify for children's tickets, we have ...
cost for adults: 2×$12.50
cost for children: 3×$8.00
total cost: 2×$12.50 +3×$8.00
Evaluation:
$25.00 +24.00 = $49.00 . . . . . . . multiplication is performed first
