c

-by-step explanation:

it would be c

here's a poem i finished a while ago. i hope you like it and that it inspires you.

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

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
