i can't be bothered to do the calculations questions however what i think for 17 is b (only answer which makes sense as there is increased expenditure.
18 is d
19 is c. (as it indicates that GDP has increased indicating that economic growth has taken place and this seems the only correct answer)

i am not sure if these answers are correct, much appreciated if you can tell me if i am wrong.

could someone write detail on how to do question 15 and 16.

my eco teacher suk, never seen any of this!!!

someone please do those two questions. thanks

It looks rong but i think 16 is (d) 2 as the graph shos a line 45o (cant see any other reason for the degree measurement) therefore 1/2 for consumption and the multiplier is
k = 1/(1-MPC)
= 1/(1/2)
= 2

Guessing 15 i'd say (a) 3750 as its closest to mi calculation(which i think is rong of 2800) as cos its the odd number out of the lot LOL.

what is a nations capital stock?
what does net investment include?
is economic growth promoted by capital widening or deepening?
what does capital widening or deepening mean?
what is a few examples of public provision of infrastructure?

i think for 16 its a), as mpc is 0.8 of income, so mps is 0.2.

k=1/mps=1/0.2=5

am i right?

i still dun get question 15...how about for pages 2, and 3 of the scans...?any answers on those?

Yea sorry thats right so 15 would be 5 * 2,000 = 10,000 which is (b)
