y = kx....with k being the constant of variation
(2,1)...x = 2 and y = 1
sub and solve for k
1 = 2k
1/2 = k <=== constant of variation is : 1/2

Answer: 0.5

Step-by-step explanation:

Given :  The number of days varies directly with the number of chores in the given table.

The equation of direct variation is given by :-

[tex]y=kx[/tex], where k is the constant of variation.

For the first row , put x= 2 and y = 1 in the above equation , we get

[tex]1=k(2)\\\\\Rightarrow\ k=\dfrac{1}{2}=0.5[/tex]

Therefore , the constant of variation : k=0.5
