A dental office gives away 2 toothbrushes to every patient who visits.  His 8 hour days are packed and each visit takes .5 hours.  How many toothbrushes does he give in a 5 day work week?
Each day he does 8/.5=<<8/.5=16>>16 visits
So he does 16*5=<<16*5=80>>80 visits a week
That means he gives away 80*2=<<80*2=160>>160 toothbrushes a week
#### 160
