Find the solution of the given initial value problem. y" - 2y' - 3y = 3te^2t, y(0) = 2, y'(0) = 0 y(t) =

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

is there more info provided? there is not enough information given in the problem
