Answer:
105
Step-by-step explanation:
base year = 2016
cost of market basket of goods in base year = $2,000
CPI for base year = 100
year 2018
cost of market basket of goods in 2018 = $2,100
CPI for 2018 = (cost of basket of goods in 2018 / cost of basket of goods in base year) x 100 = ($2,100 / $2,000) x 100 = 105
