Jay went to watch a singer in a one hour 20 minutes concert. If there was a 10-minute intermission, and all the songs were 5 minutes except for one song that lasted 10 minutes, how many songs did she sing? Give me reasons, before answering the question

The time the singer had for singing was 80 - 10 = 70 minutes. The time the singer had for singing 5 - minute songs was 70 - 10 = 60 minutes. The number of 5 - minute songs was 60 / 5 = 12 songs. The total number of songs sung is 12 + 1 = 13 songs. So the final answer is 13.
