Solve the problem and choose the correct answer.

Click here for the answer and explanation.
Since 1 hour equals 3,600 seconds, 800 hours equal (800)(3,600) seconds. Therefore, the number of 30-second commercials that the radio station plays is .
The correct answer is Choice (E).
We can use reasoning to eliminate answer Choices (A) and (B) as too small. Since a single hour is much longer than 30 seconds, the number of 30-second commercials played in 800 hours must be significantly larger than 800.
