<bot>: How much protein does Matt want to eat each day? ** He wants to eat 80*2=<<80*2=160>>160 grams of protein a day
How much protein does Matt need to eat each day? ** That means he needs 160/.8=<<160/.8=200>>200 grams of protein per day
How much protein does Matt need to eat per week? ** So he needs 200*7=<<200*7=1400>>1400 grams per week
