Matt's protein powder is 80% protein.  He weighs 80 kg and wants to eat 2 grams of protein per kilogram of body weight each day.  How much protein powder does he need to eat per week?
He wants to eat 80*2=<<80*2=160>>160 grams of protein a day
That means he needs 160/.8=<<160/.8=200>>200 grams of protein per day
So he needs 200*7=<<200*7=1400>>1400 grams per week
#### 1400
