THEORY ANSWERS
1a)
Calculate The Value Of Visible Exports
120 ,000 ,000 40,000 ,000 , 80,0000
= 240 ,000 ,000
1b)
Calculate The Balance Of Trade For The Country visible export
80,000 ,000
120 ,000 ,000
40,000 ,000
visible import
140 ,000 ,000
80,000 ,000
50,000 ,000
Total= 240 ,000 ,000 – 270 ,000 ,000
= – 30,000 ,000
1c)

i) tourism
ii) shipping and insurance
import
i) bank services

1d)
Calculate The Current Account balance of the country 120 ,000 ,000 40,000,00 45,000 ,000 60,000 ,000 80,000 ,000 / 140 ,000 ,000 80,000 ,000 50,000 ,000 60,000 ,000 40,000 ,000
= 345 ,000 ,000 – 370 ,000 ,000
= – 25,000 ,000
1e)

Pls put in a tabular form:
Under Output(kg):
0, 15, 35, 60, 85
Under variable cost($):
0, 30, 55, 75, 90
Under Total cost ($):
15, 45, 70, 90, 105
Under Total revenue($):
0, 30, 70, 120, 170
(2ai)
at output 0; marginal revenue (M. R)
= $0.00
at output 15; M.R = TR2-TR1
=30 – 0 = $30.0
at output 35; M.R = TR3 – TR2
70 – 30 = $40.0
at output 60; M.R = TR4 – TR3
=120 – 70 = $50.0
at output 85; M.R = TR5 – TR4
= 170 – 120 = $50.0
(2aii)
at output 0, marginal cost (mc) = $0.00
at output 15, mc = TC2 – TC1
= 45 – 15 = $30.00
at output 35, mc = TC3 – TC2 = 70 – 45 = $25.0
at output 60, mc = TC4 – TC3
= 90 – 70 = $20.0
at output 85, mc = TC5 – TC4
= 85 – 60 = $25.0
(2b)
(i) The firm broke even at output 60kg.
(ii) The firm made the highest profit at output level 85kg.
(iii) The firm attained equilibrium at output 35kg.
(2c)
The firm operates on a project market structure.
