The Y-intercept in this problem represents if no DVDs were bought (and only the S&H was present)
No, our friend is not correct. I know this because judging from our graph, the real cost for 12 DVDs would be $114.
It would cost $456 for 50 DVDs (that’s a lot of cash!)
(Graph seen in picture below)
Equation: y = 10x + 0
Compared to the first website, the price per DVD is seems to be higher. I know this because of two points I compared on the graphs for each website. On the first website 30 DVDs cost $276 (30, 276) while on the second website 30 DVDs cost $300. This is same for 50 DVDs. On the first website they cost $456 while on the second it cost 500.
I really hoped this helped :)
