The document discusses three graphs - A, B, and C - that could model having $5. Graph C, a downward sloping curve, was initially thought to be correct but the question asks why it is or isn't and why the other two aren't correct. The response explains that graph B, a linear positive slope, correctly represents the situation because as the amount purchased increases, the cost also increases, unlike graph C. Graph B is identified as the appropriate choice to model having $5.
Which graph models the situation if you have 5 dollars- Why and why no.docx
1. Which graph models the situation if you have 5 dollars? Why and why not the other two graphs?
-I believe it is the downward sloping curve (C) that is highlighted. But (if this is correct) why is it
the correct graph, and why are the other two not it?
Solution
I think that B is the correct graph and here's why....... B exhibits a linear positive slope that tells
us that as the amount of gallons you buy increases, the cost increases also. C doesn't make sense
for this situation because C tells us that the fewer gallons you buy, the lower the cost and in the
same light it says that the more gallons you but the less the cost. B is a strange graph and it says
that at low costs you can buy a large amount of milk and as the amount of gallons get smaller
and smaller the cost continues to increase. Once the amount of gallons levels off it still gets more
and more expensive. This graph is the obvious wrong choice. The answer to your question
should be B. As there are no further facts in the problem to say otherwise, it makes sense that
you pay more and more as you buy more gallons. I hope this helps.
