One layer of Earth's atmosphere is called the stratosphere. At one point above Earth's surface the stratosphere extends from an altitude of 13 km to an altitude of 42 km. Enter a compound inequality to
show the altitudes that are within the range of the stratosphere, use k as the altitude variable. Graph the
solutions.
What is the solution of the inequality

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

true
