(I) If the economy produces \$1 of extra output, it will:
(a) spent on domestic goods 0.8*\$1 = \$0.8 more.
(b) spent 0.2*\$1 = \$0.2 more on imports
(c) as savings S = s*Y, s = 1 - c and c = 0.8 in our case, savings will increase by (1 - 0.8)*\$1 = \$0.2.

I) If the economy produces \$1 of extra ouput it will:
First calculate the MPC= .8YD
YD= 1-.1. because of taxes.... YD=0.9
i.e MPC= .8 (.9)=.72
Spent on domestic goods= Total spent - Imports
=.72- [.2(1)]
=.72-.2
Spent on domestic goods=.52
b)Spent on imports= .2*1= \$0.2
c) Savings= 1-MPC
=1-0.72
MPS= .28
