Charmaine o tla bo a na le dingwaga di le 16 mo dingwageng di le 12 tse di tlang.  O tla bo a na le dingwaga di le kae mo dingwageng di le 4 tse di tlang?

John injured his back and needs to go to physical therapy.  He went to physical therapy for 6 weeks.  Each week he went twice for 2 hours at a time.  If the sessions cost $125 per hour how much did the physical therapy cost?
Dingwaga tsa ga Charmaine gone jaanong ke 16 - 12 = <<16-12=4>>4
Ka jalo o tla bo a na le dingwaga di le 4 + 4 = <<4+4=8>>8 mo dingwageng di le 4 tse di tlang. 
#### 8

Each week he did 2*2=<<2*2=4>>4 hours of physical therapy
So it cost 4*125=$<<4*125=500>>500 per week
This means he spent 500*6=$<<500*6=3000>>3000
#### 3000
