Answer: p = 50 s
Explanation:
Given: In each sack, there are 10 bags. In each bag, there are 5 pouches.
i.e. Total pouches in each sack = (Number of bags in each sack) x (Number of pouches in each each bag)
= 10 x 10 =50
Let p = number of pouches, and s= the number of sacks
Then, Number of p pouches in s sacks will be given by-
p = 50 s , which is the required equation.
