An online movie rental store rented out 6,816 movies one month. This was 40% less than the number of movies it rented out the previous month. The following equation represents this situation, where x represents the number of movies the store rented out the previous month.

x − 0.4x = 6,816

How many movies did the store rent out in both months combined?

Question

An online movie rental store rented out 6,816 movies one month. This was 40% less than the number of movies it rented out the previous month. The following equation represents this situation, where x represents the number of movies the store rented out the previous month.

x − 0.4x = 6,816

How many movies did the store rent out in both months combined?

anonymous · Answer

solve for x
x − 0.4x = 6,816
x=11360

add 11360 and 6,816 to get the total

anonymous · Answer

From the equation 

0.6x = 6816
x = 6816/0.6 = 11360


The store rented out x movies in a month and 40% less (OR 60% of x) the next month.
That means that in both months combined it rented out 160% of x movies.

So it rented out

(160/100)*x = (160/100)*11360 = 18176

18,176 movies in both months combined
