15 A pharmacist put 4.536 ounces of vitamin pills into bottles. She put 0.042 ounce of vitamin pills into each bottle. How many bottles did the pharmacist use for these vitamin pills? A 11 B C C D D 18

To find out how many bottles the pharmacist used for the vitamin pills, we can use the following formula: \[ \text{Number of bottles} = \frac{\text{Total amount of vitamin pills}}{\text{Amount per bottle}} \] Given: - Total amount of vitamin pills = 4.536 ounces - Amount per bottle = 0.042 ounces Now, we can substitute these values into the formula: \[ \text{Number of bottles} = \frac{4.536}{0.042} \] Let's calculate this. Calculate the value by following steps: - step0: Calculate: \(\frac{4.536}{0.042}\) - step1: Convert the expressions: \(\frac{\frac{567}{125}}{\frac{21}{500}}\) - step2: Multiply by the reciprocal: \(\frac{567}{125}\times \frac{500}{21}\) - step3: Reduce the numbers: \(27\times 4\) - step4: Multiply the numbers: \(108\) The calculation gives us: \[ \text{Number of bottles} = 108 \] Therefore, the pharmacist used **108 bottles** for the vitamin pills. Since this answer does not match any of the options provided (A, B, C, D, 18), it seems there may have been a misunderstanding in the options listed. The correct answer is 108 bottles.
