Assume that, without taxes, the consumption schedule for an economy is as shown in the table below.

Impose a progressive tax such that the tax rate is 0 percent when GDP is $100, 5 percent at $200, 10 percent at $300, 15 percent at $400, and so forth. Determine the new consumption schedule, noting the effect of this tax system on the MPC (tax inclusive) and the multiplier.
 
Instructions: In the table below, enter whole numbers for all columns except the MPC column. For the MPC column, enter two decimal places.
