PLEASE HELP WILL MAKE BRAINLIEST IF RIGHT ( NO LINKS )

i got 86 for this

hope this !

if you need an explanation just ask

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

56

step-by-step explanation:

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
