typical package of consumer goods

Suppose that the consumer price index(CPI), which measures the cost of a typical package of consumer goods, stood at 137.6in 1990 and 187.6in 2000. Let x=0 correspond to1990, and estimate the CPI in 1996 and 2003. (Assume that the data can be modeled by a straightline.)

Which linear equation best models theCPI?A.

y equals 5 x minus 137.6y=5x−137.6B.

y equals negative 5 x plus 137.6y=−5x+137.6C.

y equals 5 x plus 137.6y=5x+137.6

In 1996, the CPI would be approximately ?.

(Type an integer or a decimal.)

In 2003,t he CPI would be approximately ?

(Type an integer or a decimal.)
