Jean's bedroom is 13 feet by 13 feet. She has chosen a carpet which costs $28.60 per square yard. This includes installation.

$528.8

Step-by-step explanation:

Given data

Dimension

13 feet by 13 feet

1 ft =4.3 yard

Area= 4.3^2

Area= 18.49 yard

cost of carpet

1 yard= $28.60

18.49 yard= x

cross multiply

x= 18.49*28.60

x=$528.8

Hence the cost to cover the room is $528.8

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
