please answers everything, fix the graph as well please..

Suppose that the relationship between price, P, and quantity, Q, is given by the equation Q=505P. Which of the following equations correctly represents solving Q=505P for P? P=50+QP=105QP=50QP=505QP=1051Q Note: Price (P) is on the vertical axis and quantity (Q) is on the horizontal axis. The slope of this line is Suppose that the P in t10 Read the following state 50 refully: "When the price of a magazine subscription goes up, fewer people subscribe to the Which of the following A change in P narizes the pattern of causality suggested by this statement? The rolatinnert of thange in Q. The slope of this line is Suppose that the P in this equation refers to the price of a magazine subscription, and the Q refers to the number of magazine subscriptions sold. Read the following statement carefully: "When the price of a magazine subscription goes up, fewer people subscribe to the magazine." Which of the following best summarizes the pattern of causality suggested by this statement? A change in P causes a change in Q. The relationship between P and Q is not a causal relationship. A change in Q causes a change in P. Andrew is buying salad and pizza for a company lunch. Suppose that a bowl of salad costs $5.00, and a slice of pizza costs $3.00. Let E be the amount in dollars that Andrew. spends on salad and pizza. If Andrew buys S bowis of salad and P slices of pizza, then the total amount money he spends (E) can be represented by the equation Now rearrange the equation you wrote above so that P is E=$5.00S+$3.00P equation Suppose Andrew has $30.00 to spend on salad and pizza; Complete the following table with the values of S or P that make the equation true. Hint: To complete the first row, determine the number of plzza slices Andrew can purchase with $30.00, when the number of salad bowls he purchases is 0. Andrew is buying salad and pizza for a company lunch. Suppose that a bowl of salad costs $5.00, and a slice of pizza costs $3.00. Let E be the amount in dollars that Andrew spends on salad and pizza. If Andrew buys S bowls of salad and P slices of pizza, then the tota money he spends (E) can be represented by the equation Now rearrange the equation you wrote above so that P is written in terms of E and S. The quantity of pizza he buys can be represented by equation \begin{tabular}{c|c|c|c|c|} Suppose & P=E$5.00S \\ P=S+E \end{tabular} on salad and pizza; that is, E=$30.00. \begin{tabular}{c|c|} \hlineP=$3.00E$5.00S \\ Complete & P=$300E($5.00S) \\ P=ES \end{tabular} alues of S or P that make the equation true. Hint: To P=ES Fine the number of pizza slices Andrew can purchase with $30.00, when the number of salad bowls he purchases is 0 . Now suppose Andrew's income is cut in half : That is, he has 50% less money to spend than he did before. On the previous graph, use the blue line (circle symbols) to plot Andrew's new budget constraint. Which of the following statements best summarizes the pattern of causality captured by the graph above? Check all that apply. The relationship between S and P is not a causal relationship. A chance in E causes a shift of the budget constraint. Now suppose Andrew's income is cut in half : That is, he has 50% less money to spend than he did before.
