While on vacation in Bali, Thea bought a hat from a craftsman worth $70. If she gave the craftsman four $20 bills, how much change did she get?
E re ka Jack a kgobokantse dijana di le pedi go feta dikausu tsa dinao, o na le 60/2 = <<60/2=30>>30 dikausu tsa dinao. 
Ka kakaretso, o na le 30+60 = <<30+60=90>>90 dikausu tsa dinao le dijana. 
Peter o na le dikausu tsa dinao di le pedi go feta tsa ga Jack tseo ka kakaretso di leng 2*30 = <<2*30=60>>60 dikausu tsa dinao. 
Gape o na le dijana di le sephatlo sa tsa ga Jack tseo di leng 1/2*60 = 30 dijana.
Ka kakaretso, o na le 60+30 = <<60+30=90>>90 dikausu tsa dinao le dijana. 
Palogotlhe ya dikausu tsa dinao le dijana tse boobabedi ba nang natso ke 90+90 = <<90+90=180>>180 
#### 180 

If she gave the craftsman four $20 bills, the total amount of money she gave to the craftsman is 4*$20 = $<<4*20=80>>80.
Since the hat was worth $70, the craftsman gave her change equal to $80-$70=$10
