1. If income rose by £150 in a month and consumption rose from £150 to £250, what is the MPC (marginal propensity to consume)? 

MPC = ΔC / ΔY              (250-150) / 150 = 0.6 

1. If total disposable income in an economy was £10,800,000,000 and consumption was 8,500,000,000. What would be the APC (average propensity to consume)?
