Answer:  
 
 
Step-by-step explanation:
Given:  A bushel contains 4 pecks and a peck contains 8 quarts.
i.e.  A bush = 4 pecks
A peck = 8 quarts
Then, Number of quarts in 1 bush = 4 (8) =32
Let b = number of bushes and q = number of  quarts
Number of quarts(q) in b bushes = 32b
hence, required equation: which describes the relationship between the number of b bushels and the number of q quarts.
 which describes the relationship between the number of b bushels and the number of q quarts.
