Drag each response to the correct location on the table. Each response can be used more than once, but not all responses will be used. Consider the two exponential equations shown. Identify the attributes for each equation to complete the table. 30, 7.5%, 25%, 200, 75%, Decay, Growth, 125%

or

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
