Ricky is planning on tiling a bathroom floor. He wants to use white tiles and green tiles. The number of green tiles is to be at least 4 times as many as the number of white tiles. He needs at least 100 tiles for the entire bathroom floor.
Let x be the number of white tiles and let y be the number of green tiles.

Determine all viable solutions for x and y in terms of the context.
A
(−10,120)(−10,120)
B
(5.5,94.5) (5.5,94.5)
C
(15,90)(15,90)
D
(20,80)(20,80)
E
(80,20)(80,20)

Step-by-step explanation:

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
