The current cost of the hardcover dictionary is $304.62 .

Option (b) is correct .

Step-by-step explanation:

Formula

$CPI = \frac{(Current\ cost\ of\ the\ hardcover\ dictionary )\times 100}{Old\ cost\ of\ the\ hardcover\ dictionary}$

As given

In 1983, a hardcover dictionary cost $145.75.

If the CPI is currently 209

Put all the values in the formula

$209 = \frac{(Current\ cost\ of\ the\ hardcover\ dictionary )\times 100}{145.75}$

$Current\ cost\ of\ the\ hardcover\ dictionary= \frac{209\times 145.75}{100}$

$Current\ cost\ of\ the\ hardcover\ dictionary= \frac{30461.75}{100}$

$Current\ cost\ of\ the\ hardcover\ dictionary= 304.62\ (Approx)$

Therefore the current cost of the hardcover dictionary is $304.62 .

Option (b) is correct .
