Answer:
E. total weight = weight of crate + (weight of one apple) × (number of apples)
Explanation:
Total weight = 60 lb
Weight of crate = 4.5 lb
Weight of one apple = 0.37 lb
Let's assume, the weight of apples in the crate is "x".
x = Total weight - weight of crate ----- 1
Let's assume, the number of apples in a crate is "y".
y = x ÷ (weight of one apple) ------------ 2
[make x the subject of equation 2]
x = y × (weight of one apple) ------------ 3
[put equation 3 into equation 1]
y × (weight of one apple) = total weight - weight of crate
[make "total weight" the subject]
Total weight = y × (weight of one apple) + weight of crate.
[y is the number of apples)
Total weight = (number of apples) × (weight of one apple) + weight of crate
