Option b. The number of property crimes in 2000 was 180 × H where H is the number of households in the thousands in 2000.
The number of violent crimes in 1975 was 49 x P1 where P1 is the population in 1975 in thousands. Therfore, 180 x H/(49 x P1) = 1.45 which gives P1/H = 3.67/1.45
The quantity required is P2/H where P2 is the population in 2000.
P2/P1 = (157 + 2.3 x 50) / (157 + 2.3 x 25) = 272/214.5
Therefore, P2/H = 272/214.5 x 3.67/1.45 ~ 3.2
