Answer: 92.3%
Explanation:
The total budget which is the sum of all the expenditure by the household will be the addition of the $216 spent on firecrackers and $18 on bandages. This will be:
= $216 + $18
= $234
Price of a firecracker = $6
Price of bandages = $2 a pack
Number of firecrackers = $216/$6 = 36
Number of bandages = $18/$2 = 9
CPI market basket is 36 firecrackers and 9 bandages.
Therefore, the percentage of a household's budget spent on firecrackers in the base year will be:
= Expenditures on firecrackers/Total expenditure
= $216 / $234
= 92.3%
