(5) In 2021, supply curve of gasoline remains at Qs = 20 + 2 * P. After several fiscal stimulus packages, a surging demand for energy shifts gasoline's demand from Qd = 42 -8 * P to a higher level at Q'd = (42 + y) -8 * P, where y =M + 2. Here M is the third last digit of your student ID number. How much was the original equilibrium gas price in 2021? And how much was the new equilibrium gas price in 2021? To begin your answer, provide your value of M, y. (This question is only for those who have student ID with the last digit: 1, 3, 5, 7, 9) Tip: For the value of M, you need to get the third last digit of your student ID. For example, if the third last digit of your ID is 2. Then M = 2 and y = M + 2 =2+2=4, etc. Your M=5 Your y = M+ 5=5+5=10
