ipn [44]

Answer:

1) C(0) = 9

2) C(50) =41.5

3) C(100) =74

Step-by-step explanation:

Given : A certain economy's consumption function is given by the equation C(x) = 0.65x + 9

where, C(x) is the personal consumption expenditure in billions of dollars, and x is the disposable personal income in billions of dollars.

To find :

1) C(0)

Put x=0 in the given equation,

C(0) = 0.65(0)+ 9

C(0) = 9

2) C(50)

Put x=50 in the given equation,

C(50) = 0.65(50)+ 9

C(50) =32.5+9

C(50) =41.5

3) C(100)

Put x=100 in the given equation,

C(100) = 0.65(100)+ 9

C(100) =65+9

C(100) =74
