The houses on a city block were valued at $172,000, $164,000, $142,000, $159,000, $191,000, $124,000, and $146,000, respectively. But a public
assessor has determined that the value of each house is actually $13,000
higher than previously thought. According to the public assessor, what is the
median value of the houses?
A. $159,000
B. $165,000
C. $172,000
D. $177,000

C. $172,000

Step-by-step explanation:

Calculation for the median value of the houses

The following data was given in the question:$172,000, $164,000, $142,000,

$159,000, $191,000, $124,000, and $146,000

The first step is to Arrange the above data in ascending order

$124,000,$142,000,$146,000,$159,000,

$164,000,$172,000,$191,000

Second step is to find the Median

The Median will be the mid value, which means that $159,000 is the mid value

Based on the information given in the question we were given that a public

assessor has determined that the value of each house is actually $13,000 higher than previously thought

Hence, the Median will be = $159,000+$13,000=$172,000

Therefore the median value of the houses will be $172,000

Start by getting all terms with x on one side and all terms without on the other.

6x+7=8x-15

subtract 6x from both sides

7=2x-15

add 15 to both sides

22=2x

divide both sides by 2

11=x
