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?

a. 20,000
b. 35,990
c. 38,000
d. 180,000

igreen · Answer

10% of 18000 is 1800

So:

18000 + 1800 = 19800

So last month they sold 19,800 paperbacks.

Combined they sold: 19800 + 18000 = 37800
