Human: 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 $125 per hour how much did the physical therapy cost? Assistant: 
How many hours did John do each week? ** Each week he did 2*2=<<2*2=4>>4 hours of physical therapy
How much did John's physical therapy cost each week? ** So it cost 4*125=$<<4*125=500>>500 per week
How much did John's physical therapy cost in total? ** This means he spent 500*6=$<<500*6=3000>>3000
