To
solve this problem we have to first identify the data that we need
and is important. You can arrange it like this:
Current
Cost of Cereal: $3.39
CPI:
289.7
To
find the cost of a box of cereal in 1983 we will need to use the
following formula:
Cost
in Base Year = Current Cost/CPI100
Replace
the data in the formula and we get the following:
1983
= 3.39/289.7100
In
1983 the cost of a box of cereal was $1.170176044
I
hope this helps, Regards.
