You have a big math test tomorrow and only have an hour to study for it before you should go to bed. You feel like you might need a little practice with graphs and more practice with word problems. In your experience, it takes about 2 minutes for you to figure out the graph questions and about 4 minutes to carefully solve a word problem. You are trying to decide how many graph problems to do and how many word problems to do.
Write an equation that describes the relationship between the number of graph questions and the number of word problems you can do, assuming you study for 1 hour.
Can you complete 8 graph questions and 12 word problems in the time you have? Show your work and explain your answer.
