In an economy, the desired consumption and investment functions are given by Cd = 1 comma 000 + 0.80Y minus4 comma 000r Id = 1 comma 500minus5 comma 000r where Y is output and r is the real interest rate. Government purchases are G = 2 comma 100. The equation for desired national saving is: Upper S Subscript 1 Superscript dequalsminus3 comma 100 + 0.20Y + 4 comma 000r. Using the condition that at equilibrium, quantity of goods supplied = quantity of goods demanded, determine the real interest rates that clear the goods market when Y = 10,000 and Y = 12,000. When Y = 10,000, the equilibrium rate of interest is: r = nothing%. (Enter your response as a percentage rounded to the nearest integer.)

due to the changes the federal reserve is making the unused reserves will impact the economy by them facing inflation. inflation is definfed as the increase in pricing of a good or service but the decline of the value of money used for purchasing those items. when the economy has a high inflation rate, they are subject to money loss and hurt on the economy.
