In a private closed economy, equilibrium GDP occurs when total spending (consumption + investment) equals GDP. From the tables, at a 20% expected rate of return, the amount of investment is $20. Looking at the consumption table, for a GDP of $200, consumption is $180. Adding consumption ($180) and investment ($20) gives us $200, which matches the GDP, indicating equilibrium.
