In economics, the IS curve is a linear equation that represents all combinations of income Y and interest rates r that maintain an equilibrium in the market for goods in the economy. The LM curve is a linear equation that represents all combinations of income Y and interest rates r that maintain an equilibrium in the market for money in the economy. In an economy, suppose the equilibrium level of income (in millions of dollars) and interest rates satisfy the system of equations. Find the equilibrium level of income and interest rates. 0.05Y - 3000r = 250 0.05Y + 5000r = 650 Select the correct choice below and fill in any answer boxes in your choice. O A. The equilibrium level of income Y is $ The equilibrium interest rate r is (Type integers or decimals.) O B. There are infinitely many solutions. O C. There is no solution
