Question

The table shows the number of days required to perform a given number of chores. The number of days varies directly with the number of chores. What is the constant of variation?

Answer 1

The answer is 1/2 so C

Explanation:

Answer 2

THE CONSTANT OF VARIATION IS 1/2 or 0.5

Explanation:

Here, we want to calculate the variation constant.

From the question, we are told that number of days varies directly as the number of chores

Mathematically, that would be;

y = kx

where k is the constant of proportionality

To get the value of k, we simply divide the value of y at a point by the value of x at that point

Mathematically;

1 = 2k

which is same as

5 = 10k

Thus, the value of k would be 5/10 = 1/2 or 0.5
