Now, the average cost per night is 495....for 5 nights, it is (495 * 5) = 2475
and since the cost has tripled in the past 4 years....we can divide the regular cost by 3 to find out how much it would have cost 4 years ago
2475/3 = 825..thats for a 5 night stay 4 yrs ago
so the difference is : 2475 - 825 = 1650

Answer: choice B) 2 by 6</h3>
===============================================
How I got that answer:
Opposite sides of the rectangle are the same length, so
y = 2x-4 (horizontal sides)
3y = x+3 (vertical sides)
-----------
Start with the second equation. Replace the 'y' with (2x-4) which is from the first equation. This replacement will allow us to solve for y
3y = x+3
3(2x-4) = x+3 .. replaced y with (2x-4)
6x-12 = x+3 ... distribute
6x-12+12 = x+3+12 ..... add 12 to both sides
6x = x+15
6x-x = x+15-x ..... subtract x from both sides
5x = 15
5x/5 = 15/5 ........ divide both sides by 5
x = 3
----------
Now we know the value of x, which means we can find the value of y
y = 2x-4
y = 2*3-4 .... replace x with 3
y = 6-4
y = 2
So the horizontal side is 2 units long
The vertical side is therefore 3y = 3*2 = 6
or we can say x+3 = 3+3 = 6 getting the same answer
The value of y is a number equal to 3
Answer:
-7 and 3
-5 and 1
-3 and -1
<u><em>They all give the same total i.e. -4</em></u>
The answer will be 46,200 Hopes this helps. :)
