When x = 3 and y = 5, by how much does the value of
3x2 – 2y exceed the value of 2x2 – 3y ?

step-by-step explanation:

idk

c

step-by-step explanation:

the correct answer is c

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
