Macroeconomics question:

Consider ourADXAS model with the economy starting in long-run equilibrium at a price level of 100. Autonomous investment spending increases by $230 million. At a constant price level, this would cause aggregate demand to increase by $410 million. However, due to an upward sloping aggregate supply curve, prices rise to a price level of 105, and actual GDP increases by $235 million. What is the multiplier in this economy? (Answer to one decimal point.)
