1. Consumption changes from $210 to $300 when income increases from $500 to $600. What are the MPC, MPS, and multiplier? 2. Investment decreases by $30 and MPC= 0.75. What happens to equilibrium income? 3. Equilibrium income is $1,400 and government spending increases from $375 to $388. If MPC= 0.8, what is the new equilibrium income? 4. Investment increases by $20 and income goes from $475 to $555. What are the MPC, MPS, and multiplier? 5. Consumption increases from $600 to $700 when income increases from $1, 150 to $1,550. What are the MPC, MPS, and multiplier? 6. Investment increases by $17, government spending decreases by $6, and net exports increase by $1. If MPC= 0.9, what happens to equilibrium income 7. MPS= 0.25 and investment decreases from $1,300 to $1, 100. If equilibrium income was $2,800, what is the new equilibrium income? 8. If MPC =0.8 and equilibrium income increases by $250, by how much will spending change
