31 because if you round numbers -29 won’t work if you round it but if you round it by 31 it works
I believe it goes like this

Given:
1970 price of dish washing detergent in a bottle : $0.50
CPI
1960 = 29.60
1970 = 38.80
1980 = 82.40
(82.40 - 38.80) / 38.80 = 1.124
1.124 x 100% = 112.4% rate of increase
$0.50 * 112.4% = $0.562 is the 1980 price of the dish washing detergent.
