PART 2: SHORT-ANSWER PROBLEMBecause of Meacertain 47, the University of Oregon requirements to rise totalrevenue. The president of the University of Oregon argues that raisingtuition by a $1000 for both in-state and also out-state students will raisetotal revenue. You estimate the demand for a UO education as shown bythe adhering to graphs. Panel 1 mirrors demand by in-state students and also panel2 shows demand for out-state students. Point A in panel 1 shows thetuition and enrollment before the $1000 boost, and point B in panel 1shows the tuition and also enrollment after the boost. Point Y on panel 2reflects the tuition and enrollment for out-state students before the $1000increase, and allude Z shows the values of these variables afterward.
Price elasticity of demand also over range A to B=percent readjust in quantity demanded separated by the percentagereadjust in price= ((11-12)/11.5) / ((6-5)/5.5)= (-0.087) / (0.182)= -0.478Absolute value is less than one, so demand also is INELASTIC over thisvariety.Calculate the price elasticity of demand for out-state students over thevariety from allude Y to Z. Is demand elastic, unit elastic, or inelastic?Show your occupational to obtain full credit and also usage the midsuggest formula tocalculate the elasticity.Price elasticity of demand over array Y to Z=percent adjust in quantity demanded split by the percentagereadjust in price= ((3-4)/3.5) / ((11-10)/10.5)= (-0.286) / (0.095)= -3.011Absolute worth is better than one, so demand is ELASTIC over thisvariety. Calculate the complete revenue readjust (in dollars) we can suppose from the$1000 boost on in-state students. How does this relate to the priceelasticity of demand also for these students? (Hint: remember that totalrevenue = price*quantity) Sexactly how your job-related to acquire complete crmodify.TR = P*QAs such at suggest A: TR = $5,000 * 12,000 = $60 million At suggest B: TR = $6,000 * 11,000 = $66 millionThus the readjust in total revenue is +$6 million. Total revenue goesup once we raise tuition on in-state students which provides sense becausewe calculated that the demand also by in-state students is inelastic over thisrange of the tuition (i.e., the price) increase.Calculate the total revenue readjust (in dollars) we can intend from the$1000 boost on out-state students. How does this relate to the priceelasticity of demand also for these students? Sjust how your job-related to get full credit.TR = P*QTherefore at point Y: TR = $10,000 * 4,000 = $40 millionAt point Z: TR = $11,000 * 3,000 = $33 millionThus the change in full revenue is -$7 million. Total revenue goesdown once we raise tuition on out-state students which provides sense becausewe calculated that the demand also by out-state students is elastic over thisarray of the tuition (i.e., the price) rise.

What"s your reference to the president, offered the demand features inpanel 1 and 2 above and your calculations? We must raise tuition on in-state students, yet not on out-statestudents if our goal is to raise tuition revenue. In reality, we may have the ability to raise revenues by lowering tuition on out-state students if theirdemand also is elastic over the selection of a tuition decrease (we would have actually tocalculate this).
