ANSWER THIS FOR BRAINLIEST(20 POINTS)

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

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
