<human>:  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?
<bot>: How many minutes did the singer have for singing? ** The time the singer had for singing was 80 - 10 = <<80-10=70>>70 minutes.
How many minutes did the singer have for singing 5-minute songs? ** The time the singer had for singing 5-minute songs was 70 - 10 = 60 minutes.
How many 5-minute songs were there? ** The number of 5-minute songs was 60 / 5 = <<60/5=12>>12 songs.
How many songs did she sing? ** The total number of songs sung is 12 + 1 = <<12+1=13>>13 songs.
