Answer: It will take 20 days
Explanation:
Hi, to answer this question we have to write an equation.
The amount of boxes the store sells per day (1/5) multiplied by the number of days (x) must be equal to 4 boxes.
Mathematically speaking:
1/5 x =4
Solving for x
x = 4 / (1/5)
x = 20 days
It will take 20 days
