Plot the spectra of the message signals given in (1) via using matlab. that is, describe m1(f), m2(f), m3(f), m4(f), and m5(f). think of the reason if you see any interesting property.

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
