Question

A music store sold 1,112 music CDs one month. This was 20% less than the number of music CDs the store sold the previous month. The following equation represents this situation, where x represents the number of music CDs sold the previous month.

x − 0.2x = 1,112

How many music CDs did the store sell in both months combined?

Answer 1

Numbers of CDs sold previous month = x
20% less than x means 80% of x = 1112
0.8 x = 1112
x = 1112/0.8 = 1390
CD's sold previous month is 1390

Answer 2

Yes x -0.2x = 1112 represents the number of music CDs sold previous month.
Total CD's sold is 1112 + 1390 =2502

Answer 3

20% lessthan CDs sold in previous month
therefore consider tht 1112 is the 80 percent of no. of cds sold
therefore 80%of x=1112=1390Cds sold in perv month
x − 0.2x = 1,112
1390-278=1112
1112+1390=2052
