Hi so you would turn 25% into a decimal(0.25) and you would multiply that times 9.99! And after you get the answer you would subtract it from the 9.99!
y = a sin b(x±h) ± k
a : amplitude => take absolute value
b : angular frequency
h : horizontal shift ( phase shift). (+ left, - right)
k : mid. line or vertical shift ( + up, - down)
period: the length of one cycle
period = 2π/b ( for sines, cosines. if tangent : p = π/b)
Cut x (0;5)

A would be the correct answer! because x represents the number of miles (charged at .8) and 5.40 is a flat rate
