Each time Monica downloaded a song, she paid $0.89. If her total bill for song downloads was $19.58 last month, how many songs did Monica download?

22 songs

Step-by-step explanation:

19.58/0.89 = 22

Work Shown:

x = number of songs she downloaded

1 song = 0.89 dollars

x songs = 0.89x dollars multiply both sides by x

Since her total bill was $19.58, we know that

0.89x = 19.58

x = 19.58/0.89 divide both sides by 0.89

x = 22

She downloaded 22 songs
