Production by Mexico is the same percentage (3%) of world production for the years of interest, so the relation is

... (mexico production) = 0.03 × (world production)

Then, dividing by 0.03, we get

... (mexico production)/0.03 = (world production)

The change in world production is the difference between the amounts for the two years, so is

... (production increase) = (2007 world production) - (2000 world production)

... = 24/0.03 - 18/0.03 = (24 - 18)/0.03

... = 6/0.03 = 200 . . . . million metric tons

The appropriate choice is (D) 200.

Select the correct answer.

The equation in which b varies directly as the <em>square</em> root of c is b = 50 · √c. (Correct choice: B)

<h3>What is the equation of the direct variation between two variables?</h3>

In this problem we have a case of <em>direct</em> variation between two variables, which is mathematically described by a <em>direct proportionality</em> model, whose form and characteristics are shown below:

b ∝ √c

b = k · √c      (1)

Where k is the <em>proportionality</em> constant.

First, we determine the value of the constant of proportionality by substituting on b and c and clearing the variable: (b = 100, c = 4)

k = b / √c

k = 100 / √4

k = 100 / 2

k = 50

Then, the equation in which b varies directly as the <em>square</em> root of c is b = 50 · √c. (Correct choice: B)
