What's a "movie rental club" ?? , the last Blockbuster closed years ago. Time to get a new textbook.
number of movies rented ----- x
cost for year = 12.7 + 2.29x
average cost = (12.7 + 2.29x)/x = 2.46
2.46x = 12.7 + 2.29x
solve for x , I did not get a whole number as expected.
Your membership at a movie rental club costs
$12.7 per year. The charge for members to
rent a movie is $2.29. At the end of the year
you figured that the average cost per movie
(including the membership fee) was $2.46.
How many movies did you rent?
