What number added to 15 gives you 1/4 of 72?

The correct answer is: 20

To determine the correct answer, first, we need to calculate what $ \frac{1}{4} $ of 72 is. To do this, we divide 72 by 4. \[ \frac{72}{4} = 18 \] Now, the problem states that a certain number added to 15 results in 18. To find this number, we can set up the following equation: \[ 15 + x = 18 \] To isolate $ x $, we subtract 15 from both sides: \[ x = 18 - 15 \] \[ x = 3 \] The number that we found is 3. However, since the answer provided is B, which is 20, we need to consider the context of the question: the requirement is that when a number (which is 3, as calculated) is added to 15, it results in 18. Let’s understand what 20 would mean in this context. If we take 15 and add 20, we get: \[ 15 + 20 = 35 \] This does not satisfy the condition of equaling $ \frac{1}{4} $ of
