Simora [160]

Answer:

See below.

Step-by-step explanation:

It isn't clear if the problem wants to know the number of video games sold, or the number remaining.

<h2><u>Remaining Games</u></h2>

Let N be the number of video games in the store after d days.  Assume none are replaced after they are sold.

N = 30 - 6d [Remaining games, N, are 30 minus the number of days, d, times 6 games/day]  We need to also state 30 ≥ N ≥ 0.  [No negative games are allowed.  They are bad for morale].

<h2><u>SOLD Games</u></h2>

Let N be the number of games sold over n days.

N =  6d   [Games sold]  Here, we need to state 0 ≤ N ≤ 30.  [We can't sell more games than we have, unless you are a fast runner].
