Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used. Consider the functions given below.
P(x) = 2/3x-1
Q(x) = 6/-3x+2
Match each expression with its simplified form

c is the correct answer

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
