Let’s just say that the entire year is 365 days. So, we need to divide the APR (13.50%) to 365. This gives us a value of 0.037% and since the the billing cycle is 30 days, we need to multiply 0.037% to 30 to get it’s periodic interest rate. Therefore, the periodic interest rate is 1.11%.

Answer:
CPI in 2020 =142.7
CPI in 2019 = 100
Inflation rate = 42.7%
Explanation:
Inflation is the increase in the general price level. Inflation erodes the value of money.
Consumer Price Index(CPI ): This is the weighted average price of a basket of goods and services consumed by a typical consumer. It is used to measure the rate of inflation.
The increase in the CPI is taken to be the rate of inflation. For example, the CPI rose to 1.09 from 1.00, this implies an inflation rate of 9% within the time period in focus.
The CPI =
The price of a basket of goods in a current year ÷ Divided by the price of a basket of goods in a base year
The consumer price
Value of basket of goods in 2019 = (1000× $2) + (100× $50) + ( 500× $0.10)= 7050
Value of basket of goods in 2020= (1000× $2.50) + (100× $75) + ( 500× $$0.12)=10,060
CPI in 2020 = 10,060/7050× 100 =142.7
CPI in 2019 = 100
CPI in 2020 =142.7
CPI in 2019 = 100
The inflation rate =(142.7/100-1 ) × 100 = 42.7%
Note , we assume the CPI for 2019 is 100, since we were not provided with data to compute the price of a basket of good in 2018
CPI in 2020 =142.7
CPI in 2019 = 100
Inflation rate = 42.7%
