The table sets out the data for the Eurozone when the government's budget is balanced.

Calculate the equilibrium real interest rate, investment, and private saving.

If planned saving decreases by $\backslash (1\mathrm{.}0\backslash )$ trillion at each real interest rate, explain the change in the real interest rate.

If planned investment decreases by $\backslash (1\backslash )$ trillion at each real interest rate, explain the change in saving and the real interest rate.

The real interest rate is $7$ percent a year.

$>>$ Answer to $1$ decimal place.
