Members of a movie rental club pay a $15 annual membership fee and $2 for new release movies. nonmembers pay $3 for new release movies

a. write a system of linear equations that represent this situation

b. when is it beneficial to have a membership

A) Let, number of release movies = x
 Then, for members of a club it is: = 15 + 2x
  For non-members it is: 3x

b) It would be beneficial to have a membership when:
 15 + 2x = 3x 
 15 = 3x-2x
 x = 15

It means, It would be beneficial to have a membership when you need to release more than 15 new releases

Hope this helps!

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
