Answer
The normal cost would be $11.50
Number Explanation
1) 76 ÷ 8 = 9.5
2) 9.5 + 2 = 11.5 or 11.50
Word Explanation
First, I divided the total cost 76 by the number of people 8, to find out how much it costs per person. I got 9.5! Next, I added 2 to 9.5 because in the problem it said this is $2 less than the normal cost per person. I got 11.5! That was my answer.

$2.49 -------------------100 %
$1.99 ------------------- x %
-------------------------------------
2.49 : 1.99 = 100 : x
x = ( 1.99 * 100 ) / 2.49 = 79.9 %
100 % - 79.9 % = 21.1 % ( Decrease )
$1.99 -------------------- 100 %
$2.49 -------------------- x %
------------------------------------
1.99 : 2.49 = 100 : x
x = ( 2.49 * 100 ) / 1.99 = 125.1 %
125.1 % - 100 % = 25.1 % ( Increase )
The percents of change are not the same.
The greater change is during the increase of price ( 25.1 % > 21.1 % ).
Answer:
3,1. 4,2. 4,3. 1,1 (kkkkkkkk) no importance for kkkkkkkk
The area of the enclosed space is given by the equation
(6+2x)² = 169
We can take the square root of both sides, since 169 is a perfect square:
√(6+2x)² = √169
6 + 2x = 13
Subtract 6 from each side:
6 + 2x - 6 = 13 - 6
2x = 7
Divide both sides by 2:
2x/2 = 7/2
x = 3.5
