Answer:
6,000 Video Games
Explanation:
To find out how many video games Cloey sold on Sunday, we need to add the number of video games she sold on Friday and Saturday and then subtract that total from the total number of video games she sold over the three days:
Total number of video games sold on Friday and Saturday = 3,878 + 8,999 = 12,877
Total number of video games sold over the three days = (number sold on Friday) + (number sold on Saturday) + (number sold on Sunday)
We know that the total number of video games sold over the three days is the sum of the number sold on Friday and Saturday plus the number sold on Sunday. We can rearrange this equation to solve for the number sold on Sunday:
Number sold on Sunday = Total number sold over three days - Number sold on Friday and Saturday
Substituting in the values we know, we get:
Number sold on Sunday = (number sold on Friday) + (number sold on Saturday) + (number sold on Sunday) - (number sold on Friday) - (number sold on Saturday)
Number sold on Sunday = Total number sold over three days - Number sold on Friday and Saturday
Number sold on Sunday = (3,878 + 8,999 + X) - 12,877
Number sold on Sunday = X - 0
Simplifying this expression, we get:
Number sold on Sunday = 6,000
Therefore, Cloey sold 6,000 video games on Sunday.
