i am a mathematics teacher. if anything to ask please pm me
i think this is a systems of equations
putting this on a graph we have to equations:
y = 10x + 30
y = 20x
graph and find the intersection.
it has to be more than or equal to 3 miles i think for wreckomend
The equation is 13.95x+1.95=85.65
The answer is 6 compact discs.
