Lexi knit a total of 12 centimeters of scarf over 3 nights. After 4 nights of knitting, how many centimeters of scarf will Lexi have knit in total? Solve using unit rates.

16 centimeters.

Step-by-step explanation:

if we were two equally divide 12 centimeters by three nights, we would get 4 centimeters a night. using this method, we can determine that after four nights of knitting, at four centimeters a night, she would have knitted 16 centimeters of a scarf.

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
