1a)

Mu=Tu2-Tu1/Q2-Q1

11=p-14/2-1

11=p-14/1

P-14=11

p=11+14

P=25unit

S=43-R

S=43-40

S=3unit

Mu4=Tu4-Tu3/Q4-Q3

R-34=6

R=6+34

1bi)

at the point where the marginal ultility reaches zero ie: where the mu curve cuts the x-axis total ultility reaches it maximum point this is the saturation point.

The point of the 6th unit where marginal ultility is zero is significant

1bii)

the economic law illustrated in the marginal ultilited in the marginal ultility colunm is the law of disminshing marginal ultility which state that the satisfaction derive from consuming successive units of a commodity will be the total comsumption of the commodity increases

1ci)

if the cone if ice cost $3.00

the equilibrium condition of consumer is

Muc=pc

3=3

1cii)

the number of he consumes to attain equilibrium is 5cones

=====================

2ai)

Fixed cost = 100

*Reason*:

Total fixed cost = Total cost – Total variable cost

*At output level 4,*

Total fixed cost = 340 – (60×4)

Total fixed cost = 340 – 240 = *100*

2aii) *At output level 2,*

Total cost = Total fixed cost + Total variable cost

P = 100 + (2 × 60)

P = 100 + 120

P = 220

*At output level 5,*

Total cost = Total fixed cost + Total variable cost

Q = 100 + (5 × 70)

Q = 100 + 350

Q = 450

*At output level 1,*

Total variable cost = Total cost – Total fixed Cost

(R × 1) = 190 – 100

R = 90

*At output level 3,*

Total variable cost = Total cost – Total fixed Cost

(S × 3) = 250 – 100

3S = 150

S = 150/3

S = 50

*Marginal cost(level 2) = Total cost(level 2) – Total cost(level 1)*

T = P – 190

T = 220 – 190

T = 30

b)

i) Decreasing: Levels 1, 2 and 3

ii) Increasing: Levels 4 and 5

c)

The relationship between the average variable cost plotted on the vertical axis and the marginal cost on the horizontal axis is a curve which slopes downwards and then gradually rises upward
