A. From the black dotted lines in the graph above, we see that, in June 2008, the price of gasoline peaked at $4 dollars per gallon and dropped to $1.7 in December of that same year. What could explain the price drop of gasoline? How about the gasoline price fluctuations that we observe along the period? B. What is the percentage change in gasoline price between June 2008 and December 2008? C. From the blue dotted lines, we see that the price of ground beef was $3.55 per pound in February 2017. However, in June 2020, the price reached its peak in the last twenty years, at $5.33 per pound. What is the percentage change in price? I D. Now suppose an average South Carolina household has a budget of $100 dollars per week to spend on pounds of ground beef (QB) and gallons of gasoline (Qc). And the price of gas (PG) is $4 dollars per gallon while the price of ground beef (PB) is $2 dollars per pound. What is the budget constraint of this household? E. From the budget constraint equation, isolate the quantity of Ground Beef (QB) on one side and move all the other terms to the other side of the equation. You now have a linear equation, what is the slope and the intercept? 3

A. From the black dotted lines in the graph above, we see that, in June 2008, the price of
gasoline peaked at $4 dollars per gallon and dropped to $1.7 in December of that same
year. What could explain the price drop of gasoline? How about the gasoline price
fluctuations that we observe along the period?
B. What is the percentage change in gasoline price between June 2008 and December
2008?
C. From the blue dotted lines, we see that the price of ground beef was $3.55 per pound in
February 2017. However, in June 2020, the price reached its peak in the last twenty
years, at $5.33 per pound. What is the percentage change in price?

D. Now suppose an average South Carolina household has a budget of $100 dollars per
week to spend on pounds of ground beef (QB) and gallons of gasoline (Qc). And the
price of gas (PG) is $4 dollars per gallon while the price of ground beef (PB) is $2 dollars
per pound. What is the budget constraint of this household?
E. From the budget constraint equation, isolate the quantity of Ground Beef (QB) on one
side and move all the other terms to the other side of the equation. You now have a
linear equation, what is the slope and the intercept?
