A popular new candy bar sells for $3 a bar. There are small boxes that hold 3 bars, and the local store has 3 of the boxes. How much money are all of these candy bars worth?

$81
$27
$3
$9

The correct answer is $27.

There are 3 boxes, and each box holds 3 bars. Therefore, there are a total of 3 x 3 = 9 candy bars.
Since each candy bar sells for $3, the total value of all the candy bars is 9 x $3 = $<<9*3=27>>27.
