The percent increase in the price index from 1960 to 1970
is:
% increase in price index = (38.8 – 29.6) * 100% / 29.6
% increase in price index = 31.08%
Therefore the price of a dozen tangerines in 1970 (X) is:
31.08 = (X - $0.31) * 100 / $0.31
<span>X =
$0.41</span>

Step-by-step explanation:
(x³ - x² + x² - x + x - 1 + 1 + 1)/(x - 1)
[x²(x-1) + x(x-1) + 1(x-1) + 2]/(x-1)
(x²+x+1) + 2/(x-1)
