Answer: A add the equations and C: Subtract the bottom equation from the top equation.
Step-by-step explanation: By adding the equations, you are left with
12x=8 which successfully eliminates the y values and subracting the bottom equation from the top equation.
Hope this helps! :)
The reasonable estimate of the current customer price index is 195. The option B is the correct option.
<h3>Customer price index</h3>
Customer price index is the price index which measures the weight average of price of basket of customers goods or services.
It can be given as,
![\rm CPI_t=\dfrac{C_t}{C_0}\times 100](https://tex.z-dn.net/?f=%5Crm%20CPI_t%3D%5Cdfrac%7BC_t%7D%7BC_0%7D%5Ctimes%20100)
Here
is the cost of market basket in current period and
is the cost of market basket in the base period.
Cost of market basket in current period is
![\rm C_t=15.66+119.75+23.99+37.50\\\\C_t=196.9](https://tex.z-dn.net/?f=%5Crm%20C_t%3D15.66%2B119.75%2B23.99%2B37.50%5C%5C%5C%5CC_t%3D196.9)
Cost of market basket in 1983 is,
![\rm C_0=8.85+71.25+13.95+22.7\\\\C_0=116.8](https://tex.z-dn.net/?f=%5Crm%20C_0%3D8.85%2B71.25%2B13.95%2B22.7%5C%5C%5C%5CC_0%3D116.8)
Substitute all the values in the formula
![\rm CPI_t=\dfrac{C_t}{C_0}\times 100\\\\\rm CPI_t=\dfrac{196.9}{116.8}\times 100\\\\\rm CPI_t=1.685\times 100 \\\\ CPI_t=168.5\\\\\rm CPI_t= 170 \ \rm approx](https://tex.z-dn.net/?f=%5Crm%20CPI_t%3D%5Cdfrac%7BC_t%7D%7BC_0%7D%5Ctimes%20100%5C%5C%5C%5C%5Crm%20CPI_t%3D%5Cdfrac%7B196.9%7D%7B116.8%7D%5Ctimes%20100%5C%5C%5C%5C%5Crm%20CPI_t%3D1.685%5Ctimes%20100%20%5C%5C%5C%5C%20CPI_t%3D168.5%5C%5C%5C%5C%5Crm%20CPI_t%3D%20170%20%5C%20%5Crm%20approx)
Thus the value of current CPI is 168.5 which is near about the 170.
Hence, the reasonable estimate of the current customer price index is 195. The option B is the correct option.
