The prices of consumer goods do not always exactly follow the CPI. The following chart shows several consumer items, along with
zloy xaker [14]

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

Here \rm C_t is the cost of market basket in current period and \rm C_0 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

Cost of market basket in 1983 is,

\rm C_0=8.85+71.25+13.95+22.7\\\\C_0=116.8

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

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.

Which statement best illustrates using the vertical line test to determine if the graph below is a function of x ?
