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=<T>divide(8, 0.5)=16.0 visits
So he does 16*5=<T>multiply(16, 5)=80 visits a week
That means he gives away 80*2=<T>multiply(80, 2)=160 toothbrushes a week
