A bookstore sold 18,000 paperbacks one month. This was 10% less than the number of paperbacks the store sold the previous month. The following equation represents this situation, where x represents the number of paperbacks sold the previous month.


x - 0.1x = 18,000


How many paperbacks did the store sell in both months combined?

The answer is $38,000

(1) Calculate how many paperbacks are sold the previous month:
x - 0.1x = 18000
1x - 0.1x = 18000
0.9x = 18000
x = 18000 / 0.9
x = 20000

(2) Sum up the number of paperbacks sold in both months:
18000 + 20000 = 38000

Answer:

Step-by-step explanation:

The answer is $38,000


(1) Calculate how many paperbacks are sold the previous month:

x - 0.1x = 18000

1x - 0.1x = 18000

0.9x = 18000

x = 18000 / 0.9

x = 20000


(2) Sum up the number of paperbacks sold in both months:

18000 + 20000 = 38000
