Question: 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? Think carefully first, then make a decision:
He wants to eat 80 * 2 = 160 grams of protein a day. That means he needs 160 / .8 = 200 grams of protein per day. So he needs 200 * 7 = 1400 grams per week. So the answer is 1400.
