Question

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?

Answer 1

:)

Answer 2

Since 0.9x = 18,000,
x = 18,000/0.9 = 180,000/9 = 20,000

Answer 3

Where did you get 16,200 from?

Answer 4

That answer is wrong.

The correct answer for total books during both months is 18,000 + 20,000 = 38,000.

Answer 5

sorry messed up.
