<human>:  Three teenagers are playing soccer on the weekend. Richie, the first teenager, scored 20 more goals than Mark and scored 45 more goals than Anna. If Richie scored 80 goals, how many goals did all three teenagers score?
<bot>: How many goals did Mark score? ** If Richie scored 80 goals, which is 20 more goals than Mark, Mark scored 80-20 = <<80-20=60>>60 goals.
How many goals did Richie and Mark score? ** The combined number of goals scored by Richie and Mark is 60+80 = <<60+80=140>>140
How many goals did Anna score? ** Richie also scored 45 more goals than Anna, which means Anna scored 80-45 = <<80-45=35>>35 goals.
How many goals did all three teenagers score? ** All three teenagers scored 140+35 = <<140+35=175>>175 goals.
