Answer:

cost of house in 1970= $33855.82

Step-by-step explanation:

in this question we have given,

in 1980  consumer price index,[tex]I_{1}[/tex] = 82.4[/tex]

cost of house in 1980,[tex]=71,900

CPI  in 1970,[tex]I_{2}[/tex]= 38.8

we have to determine cost of house in 1970,[tex]C_{2}[/tex]=?

Formula used

[tex]\frac{C_{2}}{C_{1}} =\frac{I_{2}}{I_{1}}[/tex] ............(1)

put values in equation (1)

[tex]\frac{C_{2}}{71900}  =\frac{38.8}{82.4} \\C_{2}=33855.82[/tex]
