(a) a bag of trail mix weighs 2 lb. by weight, 20% of the bag is oats. how many pounds is the oats portion of the trail mix? write an equation for the situation and label the “part,” “whole,” and “percent.” (b) what is the weight of the oats in the trail mix? show your work! 20 points ! you can get brainliest this is my second freakin time posting this im wasting points

PART A
 First we define the variables:
 x: number of pounds in the bag
 y: number of pounds of oats
 The equation to find the number of pounds of oats in the bag is:
 y = (20/100) x
 Simplifying:
 y = (1/5) x
 (1/5): Represents that 20% of the weight of the bag is oatmeal.
 
 y = (1/5) x

 PART B
 Using the equation of part A, we have:
 y = (1/5) (2)
 y = 0.4 lb
 
 0.4 lb corresponds to the oat weight of the 2 lb that the bag weighs

3 1/3 lbs   2 2/3 times 1 1/4
