I’m pretty sure the answer should be 16n.
This is because for each video game, it is 16 dollars meaning you multiply the number of video games by 16 to get the total cost of however many video games you buy.
For ex.
If I but 3 videos games, each for 16 dollars, how much would it cost?
n=3
You can do it like
16+16+16
Or the same thing
(16)(3)
They both equal the same thing but 16n is the simplest way to put it. Hope that helps explain it.
