For example, a 10% decrease is equivalent to multiplying the original number by the factor 0.9. This is equal to (100-10)/100. In general, reducing something by a factor of "x" percent is equivalent to multiplying by a factor of (100-x)/100. Note that with some practice, you should be able to do all the calculations in your head, at least for a whole-number percentage.For an increase, change the minus to a plus - that's all.

What are MPC and MPS?
MPC is the Marginal Propensity to Consume. You can find the MPC by taking the change in consumption divided by the change in disposable income. Likewise, MPS is the Marginal Propensity to Save. You can find the MPS by taking the change in savings divided by the change in disposable income. It is useful to know when you want to find out what the multiplier is. Multiplier = 1/MPS or 1/(1-MPC)
