Mathematics: The market price of a house is directly proportional to the total area of the house in square feet. if the price of a 1,500 square foot home is $300,000 what is the price of a 2,000 square foot home?

Area= 1/2(height)×(base↓1+base↓2)Area=1/2(3)×(8+11)Area=1/2(3)×(19)Area=1/2(57)Area=57/2 OR 28.5Thus, the area of the trapezium is 28.5inches^2...

The price of a 2,000 square foot home is $\$400,000$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

x -----> the total area of the house in square feet

y -----> the price of the house

we have

The point (1,500,300,000)

Find the constant of proportionality k

k=y/x

substitute

k=300,000/1,500=200

The direct equation is equal to

y=200x

For $x=2,000\ ft^{2}$

Find the value of y

substitute the value of x in the equation

y=200(2,000)

$y=\$400,000$
