A pilot does a trick at a height of 15,000 feet in the air. Which choice shows that
height?

the answer will be

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

0.5?

hope your goes well, here's a turkey
