Private saving $ 2,500.

Public saving $ - 200.

National saving $2,300.

Investment is equal to saving = 2,300.

r = 10 percent.

Explanation:

Private saving is equal to (Y - C - T) = 10,000 - 6,000 - 1,500 = 2,500.

Public saving is equal to (T - G) = 1,500 - 1,700 = - 200.

National saving is equal to (Y - C - G) = 10,000 - 6,000 - 1,700 = 2,300.

Investment is equal to saving = 2,300.

The equilibrium interest rate is found by setting investment equal to 2,300 and solving for r:

3,300 - 100r = 2,300

100r = 1,000.

r = 10 percent.
