Hii
Now, in order to figure out which graph it is, we need to solve the problem.
Say someone bought 1 cup of orange juice. That would be 2$. Say they wanted a refill,that would be 3$. And so on
The first graph states that they got 5 refils, so the 2$ to get the orange juice, plus 5. That would be 7$. So the first graph is incorrect.
The second graph states that they got 9 refills. So the 2$ to get the orange juice, then 1$ for each refill, so 9$. So 11$.
The third graph states that someone got 4 refills. So, 2$ to get the cup. Then an extra 1$ for every refill. So 4$,plus 2$ is 6$
The fourth graph states that they got 8 refills. So the 2$ to get the cup, plus the 1$ each refill, since they got 8 refills, it would be 8$, So 10$.
Since the fourth graph was the only graph that showed the right cost of orange juice, this is correct
Answer: Graph 4
Hope this helps!
