Astore had 4 boxes of video games. how many days would it take to sell the games if each day they sold 1/5 of a box?

It will take 20 days

Step-by-step 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  

Feel free to ask for more if needed or if you did not understand something.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
