Answer and Explanation:
The computation is shown below:
Reference base year is 2000 and as it's the base year, So the CPI is 100.
Now
The prices have risen by 187% by 2016 means the CPI is
= 100 + 187% of 100
= 287.
And,
There is 3.4% inflation in 2017 that means prices have increased by 3.7% in 2017 compared to 2016.
Now
CPI is 287 + 3.4% of 287
= 296.758
CPI in 2017 = 296.758
In 2018, inflation is 3.7%,
CPI = 296.758 + 3.7%
= 307.74
CPI in 2018 = 307.74
In 2019, CPI is 318, which is approx 3.3% higher than as compared to the year 2018 so
Brazil's cost of living rised in 2019.
CPI of Brazil in 2017 is 296.76
CPI of Brazil in 2018 is 307.74
So,
Brazil's cost of living increases every year
