Answer :
To determine the Consumer Price Index (CPI) for 2014 and the inflation rate, we can follow these steps:
1. Calculate the cost of the basket for the base year (2012):
- The price of an apple in 2012 is \[tex]$2, and the number of apples consumed is 3. \[ \text{Cost of apples in 2012} = 2 \, (\text{price per apple}) \times 3 \, (\text{number of apples}) = 6 \] - The price of an orange in 2012 is \$[/tex]3, and the number of oranges consumed is 2.
[tex]\[ \text{Cost of oranges in 2012} = 3 \, (\text{price per orange}) \times 2 \, (\text{number of oranges}) = 6 \][/tex]
- Total cost of the basket in 2012:
[tex]\[ \text{Total cost in 2012} = 6 \, (\text{cost of apples}) + 6 \, (\text{cost of oranges}) = 12 \][/tex]
2. Calculate the cost of the basket for the year 2014:
- The price of an apple in 2014 is \[tex]$5, and the number of apples consumed is 1. \[ \text{Cost of apples in 2014} = 5 \, (\text{price per apple}) \times 1 \, (\text{number of apples}) = 5 \] - The price of an orange in 2014 is \$[/tex]5, and the number of oranges consumed is 2.
[tex]\[ \text{Cost of oranges in 2014} = 5 \, (\text{price per orange}) \times 2 \, (\text{number of oranges}) = 10 \][/tex]
- Total cost of the basket in 2014:
[tex]\[ \text{Total cost in 2014} = 5 \, (\text{cost of apples}) + 10 \, (\text{cost of oranges}) = 15 \][/tex]
3. Calculate the Consumer Price Index (CPI) for 2014:
- The CPI is calculated as:
[tex]\[ \text{CPI}_{2014} = \left( \frac{\text{Total cost in 2014}}{\text{Total cost in 2012}} \right) \times 100 \][/tex]
- Substituting the values:
[tex]\[ \text{CPI}_{2014} = \left( \frac{15}{12} \right) \times 100 = 1.25 \times 100 = 125 \][/tex]
4. Calculate the inflation rate from 2012 to 2014:
- The inflation rate is given by:
[tex]\[ \text{Inflation rate}_{2014} = \left( \frac{\text{CPI}_{2014} - 100}{100} \right) \times 100 \][/tex]
- Substituting the CPI value:
[tex]\[ \text{Inflation rate}_{2014} = \left( \frac{125 - 100}{100} \right) \times 100 = 0.25 \times 100 = 25\% \][/tex]
Based on the calculations, the CPI for 2014 is 125, and the inflation rate from 2012 to 2014 is 25%. The correct answer is:
E. [tex]\( 125 \, \text{CPI}, 50.60 \, \text{percent inflation} \)[/tex]
