Question

Jennifer pays $12.50 a month for Amazon Prime and pays extra every time she rents a movie. One month she rented 1 movie and paid $17.75. Another month she paid $49.25 and rented 7 movies.

Answer 1

Answer: y=5.25x+12.50

Step-by-step explanation:

The original 12.50 is how much she pays each month regardless of rented movies, it is the 0 value and doesn't change. Each rented movie costs 5.25 (17.75-12.50=5.25) and that value would be multiplied by the amount of movies she rents that month, and then added onto the original base value.

Answer 2

First of all to find out how much each movie cost .
17.75-12.50 = $5.25
So Jennifer paid one month $12.50 for Amazon Prime plus $5.25 = $17.75
Next month 5.25 x 7 movies = $36.75 plus 12.50 for Amazon Prime = $49.25
So to recap : one month pays $12.50 for Prime and $5.25 for one movie . Next month paid $12.50 for Prime and 7 movies totalling $36.75
