An online movie rental company charges $ 18 per month to watch up to 20 movies during that month. Milly can pay the fee of $18 per month or a 6-month fee of $ 102 for the same number of movies per month. Which choice will cost Milly less over a 6month period

Respuesta :

It is cheaper to pay the six month at once because if she pays $18 she will pay a total of $108.
