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?
Let's think step by step.
35
There are 3 + 1 = 4 people in the house.

So they drink 4 * 2 = 8 cups of coffee a day.

That means they use 8 *.

5 = 4 ounces of coffee a day.

So they use 4 * 7 = 28 ounces of coffee a week.

So he spends 28 * 1.

25 = $35.

Final answer: 35
