Describe each function as a transformation of the natural logarithm function ) = ln(x).
) = log5(25x)

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

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

look at the picture i have filled out a table for it. hope this .
