Answer #12 , 13, or 14. you so much

12. The equation would be y=$2.50x+20. For 15 videos rented the price for the movies would be $37.50, when you add the $20 membership fee, the total would be $57.50. For the last question the answer is 19 movies because you put 67.50 into the y position. You subtract the $20 membership fee and you're left with 47.50. Now, you want to get everything away from x, so you divide each side by $2.50. You're left with 19 movies as your answer.
