Question 237588
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.
