Question

Suppose Dave has a certain amount of money to spend on pizza and soda. The graph below shows the amount of pizza and soda he can afford with that amount of money. (Economists call this a budget line or budget constraint.) Based on the budget constraint shown on the graph, how much money does Dave have? (Hint: Another way of thinking about this is to realize that the graph shows the equation you selected above for a certain, specific value of E. What is that value?) $4 $40 $14 $9 $30 Graphs of equations with three variables Dave is buying pizza and soda. Suppose that a slice of pizza and a can of soda each cost $5. Let E be the amount in dollars that Dave spends on pizza and soda. If Dave buys P slices of pizza and S cans of soda, which of the following equations correctly describes the amount of money he spends? 5E = P + S E = 5P + 5S E = P + 5S E = P + S E = 5P + S Now rearrange the equation you wrote above so that S is written in terms of E and P. Which of the following is correct? S = E - P S = 5E - 5P S = E - 5P s= (1/5)E -p S = S = P + E Suppose Dave has a certain amount of money to spend on pizza and soda. The graph below shows the amount of pizza and soda he can afford with that amount of money. (Economists call this a budget line or budget constraint.) (Hint: Another way of thinking about this is to realize that the graph shows the equation you selected above for a certain, specific value of E.

Adjust the graph to show what happens to his budget constraint. (To do so, position your cursor over any dots outlined in red and drag to the desired position. Dots will snap to their new positions.) Which of the following statements best summarizes the pattern of causality captured by the graph above? Check all that apply. The relationship between P and S is not a causal relationship. A change in S causes a change in P. A change in P causes a change in S. A change in E causes a shift of the budget constraint Attempts:

Explanation / Answer

For qs19 E=5P+5S and S=1/5E-P.For rest I think some data is missing.Here from graph we can conclude 4x=4y =>x=y where x is cost of pizza and y is cost of soda.Also P+S=4 from graph
