Question: James replaces the coffee for the household.  There are 3 other people in the house and everyone drinks 2 cups of coffee a day.  It takes .5 ounces of coffee per cup of coffee.  If coffee costs $1.25 an ounce, how much does he spend on coffee a week? Is final answer 35?
Answer: There are 3+1=<<3+1=4>>4 people in the house
So they drink 4*2=<<4*2=8>>8 cups of coffee a day
That means they use 8*.5=<<8*.5=4>>4 ounces of coffee a day
So they use 4*7=<<4*7=28>>28 ounces of coffee a week
So he spends 28*1.25=$<<28*1.25=35>>35
#### 35
