A data analyst is working with a
data frame named retail. It has
separate columns for dollars
(price_dollars) and cents
(price_cents). The analyst wants to
combine the two columns into a
single column named price, with
the dollars and cents separated by
a decimal point. For example, if the
value in the price_ dollars column is
10, and the value in the price_cents
column is 50, the value in the price
column will be 10.50. What code
chunk lets the analyst create the
price column?
