Answer = (1)
Correct Answer
Explanation
We will carefully read the problem, looking for a key word or phrase. Key words and phrases indicate which arithmetic operations should be used to solve the problem.
The key phrases 62 less indicates subtraction. We translate the words of the problem to numbers and symbols.
The number of oldies radio stations in 2007 is the number of oldies radio stations in 2005 less 62.
The number of oldies radio stations in 2007 = 773 - 62
Use vertical form to perform the subtraction
\( \begin{array}{r} \phantom{-}\,773\\ -\phantom{-}\underline{62}\\[4pt] \phantom{-}\,711 \end{array} \)
In 2007, there were 711 oldies radio stations in the United States.
