Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
t = total
m = meat
f = fat
m = 300
f = .2*t
t = m + f
substitute 300 for m and .2*t for f in equation t = m + f to get:
t = 300 + .2*t
subtract .2*t from both sides of the equation to get:
.8*t = 300
divide both sides by .8 to get:
t = 300/.8 = 375
you can add 75 pounds of fat to 300 pounds of meat to meet the requirement.
total becomes 375
fat equals 20% of 375 equals 75
meat equals 80% of 375 equals 300.
